Giriş ve Amaç: Günümüzde artan teknoloji kullanımı nedeniyle gelişim çağındaki bireylerin teknolojik cihazlar ve internette geçirdiği zamanın kontrolsüzlüğü postüral rahatsızlıklara sebep olabilmektedir. Bu çalışmanın amacı; 18 yaş altı iki farklı yaş grubunda ki bireylerin mobil teknoloji ve bilgisayar kullanım alışkanlıklarını incelemek ve postürlerini karşılaştırmaktır.
Gereç ve Yöntemler: Çalışmaya 7-12 yaş grubu (Grup 1, n=48) ve 12-18 yaş grubundan (Grup 2, n=40) toplam 88 sağlıklı birey dahil edildi. Değerlendirmede katılımcıların sosyo-demografik özellikleri, vücut kütle indeksleri ile bel çevresi ölçümlerini içeren ve mobil teknoloji ve bilgisayar kullanım özelliklerini sorgulayan bir araştırma anket formu kullanıldı. Katılımcılar ayrıca New York Postür Değerlendirme Testi (NYPDT) ile değerlendirildi.
Bulgular: Katılımcıların yaş ortalaması Grup 1 için 9,94±1,29 yıl iken, Grup 2 için 14,33±1,94 yıl idi. Katılımcıların bilgisayarla en çok vakit geçirdikleri aktivite; Grup 1 için oyun oynamak (%54,2), Grup 2 için ise müzik dinlemek (%60) idi. Katılımcıların cep telefonunu en çok hangi aktivite için kullandıkları incelendiğinde; Grup 1’in oyun oynamak (%37,5), Grup 2’nin ise internette serbest zaman geçirmek (%77,5) amacıyla kullandığı görüldü. İki grup arasında NYPDT skoru açısından Grup 1 lehine anlamlı bir fark olduğu belirlendi (p=0,0001).
Sonuç: Gelişim dönemindeki bireylerin teknoloji kullanım özellikleri ve postüral düzgünlükleri incelendiğinde, artan yaş ile teknoloji kullanımının da arttığını görmekteyiz. Daha büyük yaş grubundaki bireylerin teknolojik cihazları internet kullanımı gibi sebeplerle ve daha uzun sürelerle kullanmalarının postürlerini olumsuz etkilediğini düşünmekteyiz.

В статье приведены результаты первого опыта сравнительных исследований состояния ротовой жидкости и буккального эпителия у 12 пациентов, страдающих болезнью Альцгеймера, иу 12 лиц без каких-либо признаков когнитивных нарушений. В процессе исследования изучены корреляции провоспалительных и противовоспалительных факторов ротовой жидкости, основных цитологических изменений буккального эпителия с результатами, полученными при нейропсихологическом тестировании с помощью шкал MMSE и ADAS-COG. Данное сравнительное исследование связано с предположением об общности эктодермального происхождения нервной ткани и буккального эпителия, чем могут быть обусловлены системные патологические изменения в тканях единого зародышевого эмбрионального листка. Получены результаты, свидетельствующие о специфичности патологических изменений в ротовой жидкости и буккальном эпителии для болезни Альцгеймера, что позволяет использовать исследование этих материалов для получения дополнительных диагностических маркеров этого заболевания.
The article presents the results of the first experience of comparative studies of the state of the oral fluid and buccal epithelium in 12 patients suffering from Alzheimer’s disease, and in 12 individuals without any signs of cognitive impairment. In the course of the study, the correlative relationships of pro-inflammatory and anti-inflammatory factors of the oral fluid, the main cytological changes of the buccal epithelium with the results obtained during neuropsychological testing using the MMSE and ADAS-COG scales were studied. This comparative study is associated with the assumption of a common ectodermal origin of the nervous tissue and buccal epithelium, which may be due to systemic pathological changes in the tissues of a single embryonic embryo leaf. The results obtained indicate the specificity of pathological changes in the oral fluid and buccal epithelium for Alzheimer’s disease, which allows us to use the study of these materials to obtain additional diagnostic markers of this disease.

В отечественной и зарубежной специализированной литературе отсутствуют исследования, посвященные изучению факторов риска развития неблагоприятного исхода у пациентов старшей возрастной группы с инсультассоциированной нозокомиальной пневмонией. Цель исследования - изучение факторов риска развития неблагоприятного клинического исхода у пациентов пожилого и старческого возраста с нозокомиальной пневмонией на фоне ОНМК. В исследование были включены 247 пациентов пожилого и старческого возраста (139 мужчин, 108 женщин, средний возраст - 74,1±6,3 года), госпитализированных с признаками ОНМК по ишемическому или геморрагическому типу. Согласно модели бинарной логистической регрессии, статистически значимо ассоциированы с развитием неблагоприятного исхода у изучаемой группы респондентов следующие параметры: возраст свыше 75 лет (p=0,011), степень инвалидизации по шкале mRS 3 (р=0,009), а также уровень С-РБ >100 мг/л (р=0,023) и мочевины >7 ммоль/л (р=0,044). Для снижения частоты встречаемости неблагоприятного клинического исхода у пациентов старшей возрастной группы с инсульт-ассоциированной нозокомиальной пневмонией необходимо верифицировать перечисленные выше клинико-лабораторные параметры на ранних этапах госпитализации.
In the domestic and foreign specialized literature, there are no studies devoted to the study of risk factors of mortality in the older age patients with stroke-associated nosocomial pneumonia. The purpose of the study was to study the risk factors of adverse clinical outcomes in elderly and senile patients with stroke-associated nosocomial pneumonia. The study included 247 elderly and senile patients (139 men, 108 women, mean age - 74,1±6,3 years) who were hospitalized with signs of ischemic or hemorrhagic stroke. According to the binary logistic regression model, the following parameters are statistically significantly associated with adverse clinical outcomes in the studied group of respondents: age over 75 years (p=0.011), degree of disability according to mRS ≥3 (p=0,009), and C-reactive protein levels over 100 mg/l (p=0,023) and urea more than 7 mmol/l (p=0,044). In order to reduce the incidence of adverse clinical outcomes in patients of the older age group with stroke-associated nosocomial pneumonia, it is necessary to verify the above clinical and laboratory parameters at the early stages of hospitalization.

В статье рассмотрен феномен «внутриутробного программирования», в значительной степени определяющий дальнейший жизненный цикл и вероятность развития ряда возраст-ассоциированных патологических процессов. С позиций современной науки при использовании большого литературного материала обсуждается возможность формирования патологического (ускоренного) старения на самых разных этапах онтогенеза. В тесной взаимосвязи обсуждаются причины, механизмы и фенотипические проявления ускоренного старения и возможности ранней, начиная с перинатального периода, диагностики и прогнозирования возраст-ассоциированных патологий.
This article examines the phenomenon of «intrauterine programming», which largely determines the further life cycle and the likelihood of developing a number of age-associated pathological processes. The possibility of the formation of pathological (accelerated) aging at various stages of ontogenesis is discussed with the use of large literary material from the standpoint of modern science. The reasons, mechanisms and phenotypic manifestations of accelerated aging and the possibilities of the earliest one, its diagnosis starting from the perinatal period, and prediction of age-associated pathologies are discussed in close interrelation.

On Finite Subnormal Cayley Graphs
Authors: Song Shu Jiao 
Published: September 2021

In this paper we introduce and study a type of Cayley graph – subnormal Cayley graph. We prove that a subnormal 2-arc transitive Cayley graph is a normal Cayley graph or a normal cover of a complete bipartite graph $\mathbf{K}_{p^d,p^d}$ with $p$ prime. Then we obtain a generic method for constructing half-symmetric (namely edge transitive but not arc transitive) Cayley graphs.
Сargo carrying capacity calculation for combined ships in optimization problem for ship’s main elements
Authors: Gulyaev Ilya A. Gulyaev , Ronnov Evgeniy P. Ronnov 
Published: September 2021

This article is devoted to the development of the cargo carrying capacity evaluation method for a combined ship of tanker/platform type. A specific feature of cargo carrying capacity calculation for such ships lies in the fact that they have two cargo compartments of different structure. The compartments are interconnected, including dimensions, and influence each other. This fact leads to the need to update the existing calculation methods when justifying the main dimensions both of tankers and of platform ships. It is proposed to include the parameters which affect the cargo carrying capacity and take into account the above mentioned influence into the cargo carrying capacity equations. This article also specifies the determination methods for these parameters in the early stages of ship designing. All this made it possible to obtain relations, the inclusion of which into the mathematic model of optimization problem for main elements of a combined ship (tanker/platform type) allows proper evaluation of all available options of main dimensions in terms of their compliance with carrying capacity for each specific cargo as well as exclusion of improper options from consideration.
An Examination of Pulsational Changes in the Classical Cepheid X Cygni

Published: September 2021

Abstract
Using an extensive archive for visual observations from the AAVSO, along with published times of maximum light, we determined a new model for the period of X Cygni. The best model is two linear fits for data before and after 1917 (JD2421512). Before that time the period is 16.38438 ± 0.00036 days. After we find a period of 16.386470 ± 0.000028 days. An examination of the O-C values for data after 1917 shows no clear evidence of a constant period change or of sinusoidal variations. The period looks to be constant. From an examination of H-alpha index measurements we find a drop in the value between data before 2013 October and data after 2014 July. This drop is not related to temperature and is likely related to mass loss in the star. Finally, we find that radial-velocity measurements match well with previously published values and show no seasonal variation over the 11 yr of data. This again seems to limit the possibility of a companion.

Abstract
We present near-infrared [Fe ii] images of four Class 0/I jets (HH 1/2, HH 34, HH 111, HH 46/47) observed with the Hubble Space Telescope (HST) Wide Field Camera 3. The unprecedented angular resolution allows us to measure proper motions, jet widths and trajectories, and extinction along the jets. In all cases, we detect the counterjet, which was barely visible or invisible at shorter wavelengths. We measure tangential velocities of a few hundred kilometers per second, consistent with previous HST measurements over 10 years ago. We measure the jet width as close as a few tens of au from the star, revealing high collimations of about 2° for HH 1, HH 34, and HH 111 and about 8° for HH 46, all of which are preserved up to large distances. For HH 34, we find evidence of a larger initial opening angle of about 7°. Measurement of knot positions reveals deviations in trajectory of both the jet and counterjet of all sources. Analysis of asymmetries in the inner knot positions for HH 111 suggests the presence of a low mass stellar companion at separation 20–30 au. Finally, we find extinction values of 15–20 mag near the source, which gradually decrease moving downstream along the jet. These observations have allowed us to study the counterjet at unprecedentedly high angular resolution and will be a valuable reference for planning future JWST mid-infrared observations that will peer even closer into the jet engine.

Published: September 2021

Abstract
This work presents an in-depth analysis of four gravitationally lensed red galaxies at z = 1.6–3.2. The sources are magnified by factors of 2.7–30 by foreground clusters, enabling spectral and morphological measurements that are otherwise challenging. Our sample extends below the characteristic mass of the stellar mass function and is thus more representative of the quiescent galaxy population at z > 1 than previous spectroscopic studies. We analyze deep VLT/X-SHOOTER spectra and multiband Hubble Space Telescope photometry that cover the rest-frame UV-to-optical regime. The entire sample resembles stellar disks as inferred from lensing-reconstructed images. Through stellar population synthesis analysis, we infer that the targets are young (median age = 0.1–1.2 Gyr) and formed 80% of their stellar masses within 0.07–0.47 Gyr. Mg ii
λλ 2796, 2803 absorption is detected across the sample. Blueshifted absorption and/or redshifted emission of Mg ii are found in the two youngest sources, indicative of a galactic-scale outflow of warm (T ∼ 104 K) gas. The [O iii] λ5007 luminosity is higher for the two young sources (median age less than 0.4 Gyr) than the two older ones, perhaps suggesting a decline in nuclear activity as quenching proceeds. Despite high-velocity (v ≈ 1500 km s−1) galactic-scale outflows seen in the most recently quenched galaxies, warm gas is still present to some extent long after quenching. Altogether, our results indicate that star formation quenching at high redshift must have been a rapid process (<1 Gyr) that does not synchronize with bulge formation or complete gas removal. Substantial bulge growth is required if they are to evolve into the metal-rich cores of present-day slow rotators.

Abstract
In this work, we present the results of the survey carried out on one of the deepest X-ray fields observed by the XMM-Newton satellite. The 1.75 Ms Ultra Narrow Deep Field (XMM175UNDF) survey is made by 13 observations taken over 2 yr with a total exposure time of 1.75 Ms (1.372 Ms after flare-filtered) in a field of 30′ × 30′ centered around the blazar 1ES 1553+113. We stacked the 13 observations reaching flux limits of 4.03 × 10−16, 1.3 × 10−15, and 9.8 × 10−16 erg s−1 cm−2 in the soft (0.2–2 keV), hard (2–12 keV), and full (0.2–12 keV) bands, respectively. Using a conservative threshold of Maximum Likelihood significance of ML ≥ 6, corresponding to 3σ, we detected 301 point-sources for which we derived positions, fluxes in different bands, and hardness ratios. Thanks to an optical follow-up that was carried out using the 10.4m the Gran Telescopio Canarias on the same field in the u′g′r′i′z′ bands, combined with WISE/2MASS IR data, we identified 244 optical/IR counterpart candidates for our X-ray sources and estimated their X-ray luminosities, redshift distribution, X-ray/optical–X-ray/IR flux ratios, and absolute magnitudes. Finally, we divided this subsample into 40 non-active sources and 204 active galactic nuclei, of which 139 are classified as Seyfert galaxies and 41 as Quasars.

Abstract
We present the results of on-the-fly mapping observations of 44 fields containing 107 SCUBA-2 cores in the emission lines of molecules N2H+, HC3N, and CCS at 82–94 GHz using the Nobeyama 45 m telescope. This study aimed at investigating the physical properties of cores that show high deuterium fractions and might be close to the onset of star formation. We found that the distributions of the N2H+ and HC3N line emissions are approximately similar to the distribution of the 850 μm dust continuum emission, whereas the CCS line emission is often undetected or is distributed in a clumpy structure surrounding the peak position of the 850 μm dust continuum emission. Occasionally (12%), we observe CCS emission, which is an early-type gas tracer toward the young stellar object, probably due to local high excitation. Evolution toward star formation does not immediately affect the nonthermal velocity dispersion.

Abstract
Asteroid Terrestrial-impact Last Alert System (ATLAS) observations of Centaur (2060) 95P/Chiron show a brightening in the apparent magnitude not due rotational light curves or phase effects. This onset or enhancement of cometary activity started after 2021 February 8 UT and continued in later observations from 2021 June 18 UT onward. Recent ATLAS observations and deeper follow-up imaging obtained using the Las Cumbres Observatory 1.0 m robotic telescope network find no confirmed signature of coma or tail-like features.
Short and Long Term Determinants of Bank Credit Growth in Sri Lanka
Authors: Dharmadasa P. D. C. S. 
Published: September 2021

The Purpose: The aim of this paper is to identify the determinants of credit growth of commercial banks in Sri Lanka during the period from 2008 to 2019. Design/ methodology/approaches: The analysis consists of macro-level data collected from monthly basis including bank-specific, macroeconomic, and monetary policy variables that affect credit growth. Co-integration test is conducted using Autoregressive Distributed Lag (ARDL) approach to determine the long-term determinants of credit growth. Findings: The results revealed that growth of money supply, non-performing loan ratio, lending rate, and inflation rate and efficiency ratio have a strong link with credit growth compared to other bank-specific variables, and therefore they can be considered as long term determinants of commercial banks’ credit growth in Sri Lanka. The findings further revealed that growth of GDP and credit growth tend to have a relationship which supports the ‘demand following’ hypothesis of finance-growth theory. All other bank specific variables indicated marginal impact on the credit growth in the short-run. Policy implications: The results suggested that the government should prioritize all growth promoting policies, because, low economic growth disturbs aggregate demand in the country. To achieve a desired growth, continuation of expansionary monetary and fiscal policies is necessary with a close coordination between them. Continuation of the monetary targeting framework of the CBSL is also necessary since money supply growth influences credit growth in the country. Originality: This research is expected to be a pioneering work in the field as studies focusing especially on credit growth are relatively limited in the Sri Lankan setting.
A cone beam computed tomographic evaluation of root canal treatment quality using periapical and endodontic status scale
Authors: Shah Sagar Jatish , Kulkarni Gaurav , Ramachandran Naren , Chandrasekhar Padmini , Podar Rajesh Satyanarain , Singh Shishir 
Published: September 2021

Background:
Cone beam computed tomography (CBCT) is a three-dimensional digital imaging which provides an image that can be viewed in multiple planes thus providing a better understanding of the anatomy of the root canal. Aim: This study aimed to evaluate the endodontic treatment quality of root-filled teeth and to determine the relationship between endodontic technical errors and complications.

Materials and Methods:
One hundred and fifty-two root canals were evaluated by CBCT from December 2017 to January 2019. Three endodontists assessed the root canals for the presence of technical errors and treatment complications using the periapical and endodontic status scale. Chi-square test and descriptive analyses were performed.

Results:
Sixty-one (40.4%) root canals had periapical radiolucency followed by 45 (29.8%) root canals with short obturations. Sixty-nine root canals (45.7%) and 45 (29.8%) root canals had nonhomogenous root canal filling and coronal seal (CS), respectively. Statistically significant association was seen with the length of the root canal filling, homogeneity, CS, and complications (P < 0.05).

Conclusions:
There was high prevalence of apical radiolucency in root-filled teeth. The presence of short obturations, poor CS, and nonhomogenous obturation led to higher prevalence of endodontic complications.
