Published: October 2020

Introduction: Oral rehabilitation is based on establishing a correct diagnosis and designing a plan to give appropriate treatment to each clinical case. Patients’ aesthetic requirements show an increasing trend in current practice. Sjögren’s syndrome and obesity can have a negative impact on a person’s quality of life, and it is therefore imperative to identify and reduce these significant barriers to paving the way for better oral health and the overall well-being of the individual. Hypertension NYHA II type patients may present oral manifestations like ageusia, burning sensation, xerostomia, lichenoid reactions or gingival hyperplasia. Case presentation: This time, at our clinic, a 71-year-old man requested a complex oral rehabilitation. He presented partial edentulism at both arches. We are talking about a non-smoking patient, with chronical medication treatment for the mentioned pathology. Conclusions: A well-controlled hypertensive patient is not a risk in clinical practice. When choosing an implant based therapy, the old age of the patient can be considered a negative factor for successful results, but it is not a strict contraindication. This case report shows the most suitable treatment solution, regarding all the advantages and disadvantages of other treatment options, represented by implant supported fixed prosthetic restaurations.
Comparative Study on Fatigue Life of CFRP Composites with Damages
Authors: Baran Marta , Synaszko Piotr , Lisiecki Janusz , Kłysz Sylwester
Published: October 2020

In this work, the compressive residual strength tests results, Compression After Impact (CAI), are presented. The specimens were made of carbon-epoxy prepreg E722-02 UHS 130-14. Two variants of specimens were tested: samples undamaged and samples with damage that was centrally introduced by a drop-weight impact, as per the ASTM D7136/7136M standard. An impactor with potential energy equal to 15J and the type of support required by the standard were used. The size of impacted damages, defined as an area of damage on a plane perpendicular to the impact direction, and the equivalent diameter were specified using the flash thermography method.

The tests were performed using the fixtures manufactured according to the ASTM D7137/7137M standard. The specimens were compressed to determine the residual strength. This value was afterwards used to specify the force levels for the fatigue tests. The fatigue tests were carried out under force control – with a sinusoidal shape, stress ratio R equal to 0.1 and frequency f 1Hz. Maximum force in a loading cycle Pmax
was being increased after each thousand of cycles N until its value was close to the residual strength determined in the previously mentioned tests. In this work, the following relationships were presented: force-displacement P-δ for both static and fatigue tests and displacement-loading cycles δ-N for fatigue tests.

A method of conducting the fatigue tests of CFRP composite was proposed, in which both the CAI specimens and CAI fixture were used. This allowed researchers to accelerate making initial comparisons between the two groups of specimens with damages – grouped relative to the way of conditioning.

Published: October 2020

Carbon fiber reinforced plastics (CFRPs) are widely used in aerospace structures due to their high stiffness, strength and good fatigue properties. They are however vulnerable to loads perpendicular to their plane and, while impacted, can suffer significant internal damage decreasing their overall strength. Detecting and sizing such damage is an important task of the non-destructive inspection (NDI) methods. This study was conducted to detect and quantify damage in a set of six impacted even rectangular CFRP specimens designed from a MiG-29 vertical stabilizer’s skin. The inspection was done using the ultrasonic (UT) method (based on mobile scanner – MAUS V) and the pulsed infrared thermographic (IRT) method. Each specimen’s inside and outside (impacted) surface was inspected separately with IRT, while the outside surface was then inspected with UT. UT provided the most precise measurements of the damage area, while the IRT inspection of the outside surface (which would be accessible on a real aircraft structure) provided underestimated values due to the damage’s depth and geometry.
Bank Risk Profiles and Business Model Characteristics
Authors: Ercegovac Roberto , Pečarić Mario , Klinac Ivica
Published: October 2020

Current research, especially after the financial crisis, highlights different key determinants of high risk bank profiles. The main aim of this paper is to test, through an empirical model, the impact of various determinants of bank business models on the bank risk with the purpose of enabling early identification of signals of risk and timely application of prudential measures. There are two basic business models for banks: market-oriented wholesale bank business model and client-oriented bank business model. In the wholesale model, a significant share of the assets is comprised of securities in the trade portfolio, the bank is strongly involved in the international financial markets, while on the income side of the bank profile, a large part is related to non-interest income. In the client related business model, classical banking is dominant, which is visible in the high share of loan-related assets, a larger share of self-financing and a larger share of income from interest-operational income in the total income structure of the bank. In the panel analysis of the empirical data, as an indicator of the bank risk profile, the stock market price to stock market price volatility ratio was used with the presumption that the market price and its volatility, with sufficiently liquid shares listed on public stock exchanges, is representative of bank risk. The analysis is conducted on a homogenous example of 20 European banks in the period 2002-2017. Following the econometric analysis, the conclusion is that banks in which business model wholesale characteristics are dominant are more exposed to business risk in periods of market shocks and, as such, represent a danger for the long-term stability of the financial sector.
Applicability of Airborne Laser Scanning in the Identification of Lake Shorelines
Authors: Ptak Mariusz , Choiński Adam , Pych Aleksandra , Piekarczyk Jan
Published: October 2020

The paper presents the applicability of LiDAR data in limnological research with respect to the identification of the shoreline of lakes, and consequently the scale of overgrowing of lakes. Data obtained from the Head Office of Geodesy and Cartography from the period 2011 2016 provided the basis for the identification of shorelines for 14 lakes of the Pomeranian Lakeland. The paper employs the orthophotomap for the determination of the range of lake vegetation. Using the line determined based on the orthophotomap and that determined based on LiDAR points, the zone of overgrowing of the analysed lakes was delineated. In all the analysed cases combined, the water surface area was found to be reduced in comparison to the shoreline identified through LiDAR scanning by 161.5 ha, suggesting a 21.2% share of vegetation in the surface area of lakes.
Characteristics of Selected Lakes with Aeolian and Karst Genesis in the Holy Cross Region
Authors: Choiński Adam , Zieliński Artur
Published: October 2020

In the belt of the Polish Uplands, including the Holy Cross Region, lakes occur sporadically. In some places, however, they are somewhat more abundant. They are usually objects with a small surface area. The majority of them have not been subject to thorough investigation. Therefore, the objective of the paper is the expansion of knowledge regarding these lakes. The paper among others presents the characteristics of several lakes with aeolian genesis located on the Przedbórz Upland in the catchment area of the Wierna River and in the Nida Basin near the towns of Busko-Zdrój and Pińczów. The study results determine the morphometric parameters of the lakes, also pointing to an exceptionally high variability of physical and chemical water properties, as well as the possibility of periodical disappearance of the lakes. Moreover, the study results provide a necessary and solid basis for further investigation of the lakes, which in the context of the observed increasingly serious water deficit and decrease in the level of surface waters and groundwaters is undoubtedly of high importance.

Published: October 2020

The aim of this study was to reveal the chemical composition of bottom sediments in karst lakes located in the northern part of Połaniec Basin (eastern part of the Nida Basin, vicinity of Staszów municipality). A field investigation was carried out in 2010 on four lakes: Duży Staw, Donica, Dziki Staw and Łajba. The contents of a very wide range of chemical elements were determined, which is a rarity. On the basis of our research, it was found that the analysed lakes differed considerably between each other in spite of their close location. In general, sediments contained fair amounts of organic substances as well as Fe, Al, Ca and Mg due to the type of source rock and soligenic lake water supply. Increased concentrations of V, Cr and Ni might be explained by the weathering of rock material. In turn, higher contents of Zn, Pb, Cu and Co in the bottom sediments from Duży Staw indicated anthropopression. The measurement results obtained in this study will allow a future comparative analysis with bottom sediments from other lakes.
“From Obedience to Freedom”. Anti-liberation Traditions and Oppression School Culture
Authors: Głowacka-Sobiech Edyta
Published: October 2020

The article seeks to show how school relationships have changed over the centuries. The main focus is on recent times, when so-called ‘school coercion’ was introduced, accompanied by military reform and the debate on violence and obedience among pupils. Yet oppression remained in schools, despite being opposed by the most prominent educators and thinkers of the period. Church institutions also supported the anti-freedom movements in schools. It is against this background that the slogan of the “new upbringing” movement is presented, which was to give a sense of freedom and respect for other people.
Students with Specific Learning Disabilities in the Higher Education System in Israel: Successes and Challenges
Authors: Mandelblit Ronit
Published: October 2020

Studies show the very high probability that a child with learning disabilities will grow up to be an adult with learning disabilities and will experience difficulties in his academic or professional studies and in the world of employment. Today, there is an increase in the number of students with learning disabilities in academic institutions in Israel and around the world, with the extent of students with learning disabilities in Israel being estimated at up to 15% of diagnosed students. The article discusses the problem that most studies address children and teens with learning disabilities, while knowledge about coping with students with learning disabilities in the higher education system is limited. Moreover, there seems to be no uniform policy on supporting these students. The article is addressed to policymakers and lawmakers in Israel’s higher education system, with the aim of presenting current support and proposing changes and improvements intended for these students.
Professional Burnout among Teachers in Regular Schools and Youth Villages in Israel
Authors: Azulay Vered
Published: October 2020

The research study addresses the burnout of teachers who teach in regular schools vs. burnout among teachers who teach in youth villages in Israel. The research participants consist of 73 teachers who work with at-risk youths in youth villages in Israel and 70 teachers who work in regular schools, making a total of 143 teachers. A 5-segment self-reporting questionnaire was distributed. The study found a difference in how teachers refer to the factors influencing their departure. In the youth villages, as the factors of support are greater, the factors of departure are more significant. Hence, it is possible to understand that the conclusion that arises from the study is that in order to prevent teacher burnout it is necessary to create many more sources of support, both in regular schools and in youth villages.

Published: October 2020

Introduction: Suicide by ligature strangulation has been rarely reported in literature. This case report was prepared to present this different method of suicide and to discuss the findings of this case in the framework of findings in literature.

Case: A 37-year old male was found dead in his home where he lived alone, with no signs of forced entry to the house. The body was lying supine on the dining table, with the feet hanging free and the head completely resting on the table. A thick, orange-coloured rope was wrapped three times around the neck and below the table where the head was resting was a 20kg demijohn full of water, with a broken rope with the same features wrapped around the neck of the bottle.

Discussion and Conclusion: The current case is unique in respect of showing the postmortem findings which could be created following the application of pressure with a force of 20kg on the airway and blood vessels. The necessity is emphasised for detailed examination of the scene to differentiate suicide from murder and of information from before death and from the autopsy to correctly establish the cause of death.

COVID-19 and vascular disorders (literature review)
Authors: Petrishchev N. N. , Khalepo O. V. , Vavilenkova Y. A. , Vlasov T. D.
Published: October 2020

The review describes pathogenesis of the disease caused by the new SARS-CoV-2 virus. It infects the human cells by linking angiotensin-converting enzyme-2 (ACE2) and a number of other receptors. The virus imbalances the renin-angiotensin system, results to vasoconstriction and acts like pro-inflammatory agent. ACE2 is exposed on the alveolar epithelium cell surface. It is the main gates for virus entering and damaging of the respiratory system resulted in an acute respiratory distress syndrome. The injuring of the pulmonary vessel endothelium is the most important part of the COVID-19 pathogenesis. ACE2 of the endothelial and smooth muscle cell surface upon the SARS-CoV-2 infection facilitates the injury of cardiovascular system. The development of endotheliitis induced by «cytokine storm» leads to the main signs of the disease and the multiple disorder of the microcirculation. The investigation of that condition has a prognostic value and determines the treatment especially in critically ill patients. Systemic endothelial dysfunction upon the COVID-19 largely triggers the hemostasis disorders. High activity of platelets adhesion and aggregation, blood coagulation in died COVID-19 patients, disorder of fibrinolysis system functional activity could be induced by the endothelium activation. The unchanged anticoagulation blood activity in the COVID-19 patients distinguishes them from the patients with disseminated intravascular coagulation. Monitoring of the hemostasis system in COVID-19 is important for the disease severity assess and its prognosis, for justin-time correction of detected deviations.

Case report (precis): Atypical delayed presentation of cervical spinal epidural abscess
Authors: Epstein Nancy E.
Published: October 2020

Background:

Older patients with spinal epidural abscesses (SEA) may present in an atypical fashion, failing to exhibit the classical triad of pain, fever, and a neurological deficit. Rather, they may be less aware of pain, fail to develop a fever, and attribute their neurological deficit to “old age.” Further, their laboratory studies may not be abnormal, and critical findings on MR (i.e., more so than CT studies) may be overlooked. Here, we present an elderly patient with severe upper extremity monoparesis whose cervical SEA was overlooked for months.

Case Description:

Over 10 months, and 6 months ago respectively, the patient had two successive MR scans ordered due to falls; both were interpreted as normal. Within the past few months, a third cervical MR, and an initial CT scan were performed; they both showed “questionable” changes (e.g. cortical irregularity/epidural air) that were largely ignored. When the patient presented to a spine surgeon with severe upper extremity monoparesis, the fourth MR clearly demonstrated a high cervical SEA. Of interest, laboratory findings were normal (e.g. white blood cell count (WBC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP)). The patient successfully underwent an anterior cervical discectomy/and fusion (ACDF); cultures grew Staphylococcus aureus, and he was appropriately managed with intravenous antibiotic therapy.

Conclusion:

This case report (precis) highlights three “teaching” points. First, elderly immunologically compromised patients may not develop the classical SEA triad of pain, fever, and a neurological deficit. Second, laboratory studies may remain normal. Third, it may take longer for abnormal findings to develop on MR/CT studies consistent with SEA in immunocompromised older patients, thus resulting in very delayed surgery.

In the linear-scaling divide-and-conquer (DC) electronic structure method, each subsystem is calculated together with the neighboring buffer region, the size of which affects the energy error introduced by the fragmentation in the DC method. The DC self-consistent field calculation utilizes a scheme to automatically determine the appropriate buffer region that is as compact as possible for reducing the computational time while maintaining acceptable accuracy (J. Comput. Chem. 2018, 39, 909). To extend the automatic determination scheme of the buffer region to the DC second-order Møller-Plesset perturbation (MP2) calculation, a scheme for estimating the subsystem MP2 correlation energy contribution from each atom in the buffer region is proposed. The estimation is based on the atomic orbital Laplace MP2 formalism. Based on this, an automatic buffer determination scheme for the DC-MP2 calculation is constructed and its performance for several types of systems is assessed.

We present a computational scheme for restricted-active-space configuration inter- action (RASCI) calculations combined with second-order perturbation theory (RASCI- PT2) on a fragment of a periodic system embedded in the periodic Hartree-Fock (HF) wavefunction. This method allows one to calculate the electronic structure of localized strongly-correlated features in crystals and surfaces. The scheme was implemented via an interface between the Cryscor and Q-Chem codes. To evaluate the performance of the embedding method, we explored dissociation of fluorine atom from a lithium flu- oride surface and partially fluorinated graphane layer. The results show that RASCI and RASCI-PT2 embedded in periodic HF are able to produce well-behaved potential energy surfaces and accurate dissociation energies.

In this study, the impact of graphene on neuronal differentiation of PC12 cells into neuron-like cells was evaluated in conjunction with electrical stimuli. First, an ITO (Indium Tin Oxide) microchip with a certain number of electrodes was fabricated using photolithography and then a chemically synthesized graphene was coated on the microchip. The electrical stimulation was applied through the ITO-microchip. Following optimization of neuronal differentiation conditions, the effect of AC and DC electrical stimulation on both bare and graphene-coated ITO-microchips for neuronal differentiation was investigated. According to the results, it was observed that electrical stimulation with direct current for 30 minutes caused a large degree of neuronal cell differentiation on the graphene coated ITO-microchips. The results were also verified by real-time qPCR.

The recent spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its association has gripped the entire community and has caused widespread public health concerns. There are various dental procedures that cause spread of the infection. There are risks due to lack of PPE, risks during dental procedure, risks involving handpiece, aerosols, droplets, during communication and contaminated surface. Minimum 30 articles were collected from Pubmed, Google Scholar. We acknowledge that due to lack of PPE, infection can spread more easily, oral surgery drills also cause aerosol and can be transmitted to the susceptible individuals. Communication between the patient and dentist has a high chance of infection transmission. Contamination from spatter and aerosol dissemination remains a significant hazard to dental personnel when high speed dental equipment is used. Dental practitioners have to be more careful while doing dental procedures as there is a high chance of risks for dentistry during covid-19 and proper guidelines should be there while doing dental procedures.

Published: October 2020

Bertahun-tahun yang lalu, telah diketahui bahwa Tripel Pythagoras dapat dikonstruksi dengan konstruksi [ ], yaitu [ ] ( ). Namun, konstruksi ini masih memiliki sedikitnya dua kekurangan, yaitu konstruksi ini masih perlu memperhatikan urutan dari sisi-sisi tegakya dan konstruksi ini tidak bisa memproduksi semua tripel pythgoras yang ada. Dalam penelitian ini, akan dibahas tentang konstruksi baru untuk tripel pythagoras yang dapat memproduksi semua tripel pythagoras yang diinginkan dan konstruksi ini juga tidak memerlukan urutan dari sisi-sisi tegaknya.
