Abstract

Objectives
The aim of this article was to present a case of premature fetal closure of the ductus arteriosus (DA) of unknown cause.

Case presentation
A 32-year-old pregnant woman came for the regular prenatal visit at 36 + 1 weeks of gestation (WG) at which oligohydramnios and premature closure of DA were revealed. Use of non-steroidal anti-inflammatory drugs was excluded by the history, although the patient had the symptoms of common cold 2 weeks before the check-up taking more than 1,000 mL of strong chamomile tea daily till the day before the prenatal visit. The patient was hospitalized at 36 + 1 weeks of gestation due to premature closure of DA and oligohydramnios (amniotic fluid index = 4.5/3), which was the indication to deliver the baby by cesarean section at 36 + 6 WG (birth weight was 2,830 g, birth length 49 cm and head circumference 34 cm, Apgar score at 1 and 5 min were 9/9). Postnatal course was uneventful, and postnatal echocardiography at 12 h of life revealed functionally closed DA and mild dysfunction of the right ventricle, which completely resolved after 7 days. The mother and the baby were discharged home healthy, and were doing well 3 months after delivery.

Conclusions
Although the cause of premature closure of DA in most of the cases will remain undetected, thorough history sometimes with unexpected events should be taken under the consideration as possible causative factor for premature DA closure, as was drinking of high quantities of chamomile tea in our case.
Expressing intent, imminence and ire by attributing speech/thought in Mongolian
Authors: Brosig Benjamin 
Published: June 2021

Abstract
Quoted clauses in which an intention is declared are cross-linguistically known to develop into clauses that directly ascribe an intention to their subjects, and further into clauses that express the imminence of an event. In Khalkha Mongolian, several quotative constructions based on the quotative verb ge- have come to ascribe intention and then developed further semantic extensions:

(i)
The pattern -x ge-, featuring a fossilized Middle Mongol future-referring participial suffix, is used in a group of constructions that cover the semantic space between future time reference, intention (initially of the current speaker), and imminence.

(ii)
Quotational clauses ending in a particular tense-aspect-evidentiality suffix (including -n) and subordinated by a linking converb ge-ž/ge-ed are often systematically ambiguous between quotation and their purposive, causal and concessive extensions. Noun phrases with similar properties additionally allow for (dedicational-)benefactive and (allocational-)functive uses.

(iii)
The pattern -n ge-, which in other Central Mongolic varieties resembles -x ge-, conveys the speaker’s disbelief and anger about an actor’s willful deeds when used in echo questions marked by -n=AA.

Based on conversational corpus data, this paper tries to provide a comprehensive picture of Khalkha Mongolian constructions in which the speaker’s awareness of the subject’s speech or thoughts is reinterpreted as attributing intentions and their derived notions.

Published: June 2021

Abstract

Objectives
The aim of this pilot psychometric study was to develop and assess the reliability, validity, and applicability of a nursing clinical assessment tool (NCAT) to assess students’ clinical performance in the clinical training.

Methods
Total of 325 forms were completed by 36 clinical raters for undergraduate nursing students who were selected using convenience sampling. International quality and safety education for nurses (QSEN) and Benson and Clark’s model guided the construction of the NCAT. Following literature review, a cross-cultural adaptation and psychometric testing were used.

Results
This newly developed tool showed substantial overall internal consistency reliability (Cronbach’s alpha = 0.74). Three factors (i.e. Care Provider, Leadership & Team Work and Professionalism and Ethical Considerations) were identified for construct validity using exploratory factor analysis (EFA).

Conclusions
This study suggests that the NCAT is a reliable, valid and applicable tool. It can be used in clinical and educational settings. Further testing of the tool in similar and different cultures is recommended.
GLM based auto-regressive process to model Covid-19 pandemic in Turkey
Authors: Alin Aylin 
Published: June 2021

Abstract

Objectives: Our objective is to propose a robust approach to model daily new cases and daily new deaths due to covid-19 infection in Turkey.

Methods: We consider the generalized linear model (GLM) approach for the autoregressive process (AR) with log link for modelling. We study the data between March 11, 2020 that is the date first confirmed case occurred and October 20, 2020. After a month of the first outbreak in Turkey, the first official curfew has been imposed during the weekend. Since then there have been curfews each weekend till June 1st. Hence, we include intervention effects as well as some outlying data points in the model where necessary. We use the data between March 11 and September 15 to build the models, and test the performance on the data from September 16 till October 20. We also study the consistency of the model statistics.

Results: Estimated models fit data quite well. Results reveal that after the first curfew daily new Covid-19 cases decrease 18.5%. As expected, effect of the curfew gets more significant once a month is past, and daily new cases cut down 24.9%. Our approach also gives a robust estimate for the effective reproduction number that is approximately 2 meaning as of October 20, 2020 there is still a risk for an infected person to cause 2 secondary infections despite all the interventions, preventions, and rules.

Conclusion: The GLM approach for AR process with log link produces consistent and robust estimates for the daily new cases and daily new deaths for the data covering almost the first year of the pandemic in Turkey. The proposed approach can also be used to model the cases in other countries.
Die Modernisierung der russischen Streitkräfte
Authors: Hackett James 
Published: June 2021

Kurzfassung
Die gegenwärtigen Streitkräfte Russlands werden seit den 90er Jahren transformiert. Die Bemühungen, das Militär zu modernisieren, neu auszurüsten und zu reformieren, führten zu Streitkräften, die heute kleiner, besser ausgestattet und besser ausgebildet sind und die auf einem höheren Stand der Einsatzbereitschaft gehalten werden als ihre sowjetischen Vorgänger. Während es anfangs das Ziel war, in begrenzten Konflikten an der russischen Peripherie einzugreifen, steht spätestens seit 2014 auch das Ziel im Vordergrund, einen größeren konventionellen Krieg mit dem Westen ausfechten zu können. Der Erfolg der Reform- und Neuausrüstungspläne wäre ohne die entsprechende Aufstockung der Budgetmittel nicht möglich gewesen. Allerdings ist die Finanzierung nach wie vor von den ökonomischen Realitäten abhängig. Alle Teilstreitkräfte haben von einer besseren Finanzausstattung profitiert. Die größten Nutznießer waren die Strategischen Streitkräfte und die Luft- und Weltraumkräfte, während die Seestreitkräfte Mühe hatten, die Zielvorgaben für Überwasserschiffe zu erfüllen. Auch die Beschaffungsziele für die Landstreitkräfte wurden in einigen Schlüsselbereichen wie bei schweren Panzern verfehlt. Der Modernisierungsprozess hat keine Streitkräfte hervorgebracht, die es bezüglich Fähigkeiten und Größe in einem längeren, uneingeschränkten konventionellen Krieg mit den Vereinigten Staaten und der NATO aufnehmen könnten, aber dies war wahrscheinlich auch nie das Ziel. Russlands politischer Führung stehen heute gut ausgerüstete konventionelle Streitkräfte zur Verfügung, deren personelles Rückgrat Berufssoldaten statt Wehrpflichtige bilden.
МІДЬ-КАРБОНОВІ НАНОКОМПОЗИТИ НА ОСНОВІ СИНТЕТИЧНИХ ГУМІНОВИХ РЕЧОВИН

Published: June 2021

Розроблено нову методику синтезу мідь-карбонового нанокомпозиту з використанням синтетичних гумінових речовин як джерела Карбону. В основу методики покладено піроліз купрум(ІІ) гумату, який проводили як у відновлюючій водневій, так і інертній атмосфері. Структуру та властивості Сu/C нанокомпозиту охарактеризовано методом рентгенівської дифракції, ІЧ-спектроскопії, просвічуючої електронної мікроскопії, елементного аналізу. Пористу структуру Сu/C нанокомпозиту досліджено методом об’ємної адсорбції азоту. В умовах синтезу формується карбонова матриця з дуже низьким ступенем впорядкованості. Встановлено, що розмірні та структурні харакеристики наночастинок міді залежать від умов синтезу і варіюються від 40 до 80 нм. Проведення синтезу у відновній атмосфері дозволяє одержати мідь-вуглецеві нанокомпозити, що не містять фази купрум(І) оксиду або купрум(ІІ) оксиду. Встановлено, що підвищення температури піролізу сприяє вдосконаленню будови кристалічної ґратки металічної фази, підвищенню ступеня карбонізації органічної складової та зміні текстурних характеристик від мезопористих до мікропористих.

Розроблено технологію отримання закваски на основі чистих культур молочнокислих бактерій без додавання хлібопекарських дріжджів та синтетичних домішок. У якості поживної суміші запропоновано цільнозернове спельтове, пшеничне та безглютенове соєве борошно. Досліджено процес ферментації закваски за фізико-хімічними показниками – піднімальною силою за кулькою та титрованою кислотністю при температурах культивування симбіозу чистих молочнокислих бактерій 22 0С та 40 0С. Для інтенсифікації процесу ферментації введено додаткові субстрати – лактулоза, сорбіт, лактоза, фруктоза у концентраціях 2, 4, 6, 8 %. Ефективність використання нуклеотиду аденозинтрифосфату було досліджено у зразках закваски за концентрацій 25, 50, 75, 100 мг/кг борошна. Досліджені зразки заквасок за якісними показниками мають стабільну форму пастоподібної консистенції з кислотністю 10–14 град., піднімальною силою за кулькою не вище ніж 25 хв., вологістю 48–50 %. Найкращими за результатами органолептичної оцінки, показниками пористості вважаються зразки функціонального хліба, виготовленого на заквасці з додаванням лактулози та аденозинтрифосфату.
Методом математичного моделювання з використанням сплайн-апроксимації встановлено оптимальні технологічні параметри для мінімізації часу технологічного циклу виведення закваски з додаванням лактулози та нуклеотиду аденозинтрифосфату. Встановлено оптимальні концентрації лактулози та нуклеотиду аденозинтрифосфату, які становлять 4.34 % та 46.7 мг/кг борошна відповідно. Дана технологія адаптована для потужних та крафтових пекарень.

Abstract
Letrozole is one of the third generation aromatase inhibitors. It is suitable for the treatment of postmenopausal patients with advanced breast cancer and early treatment of breast cancer. It is necessary to develop a rapid, reliable, selective and sensitive LC–MS/MS assay to determine letrozole in human plasma to evaluate the clinical efficacy and adverse reactions with clinical pharmacokinetic and therapeutic drug monitoring. Separation was carried out on a Kromasil-C18 column using acetonitrile-water (55: 45, v/v) as mobile phase. Detection was carried out by multiple reaction monitoring on a 3200Qtrap mass spectrometry. The method needed one-step protein precipitation procedure only, and the cycle time was 2.5 min allowing 500–550 samples per day. It was linear within 0.30–50.00 ng/mL for plasma with the limit of detection (LOD) of 0.030 ng/mL. The intra- and inter-day RSD were 5.51–8.63%, 2.28–9.95% and the RE was 0.18–1.65%. The recovery rates of letrozole and internal standard for plasma were 89.30–98.55%. Letrozole was stable under all the conditions in the study. The method was sensitive enough to quantitate letrozole over a period of 288 h after giving a single oral dose of 2.5 mg–24 Chinese healthy volunteers. The absorption of letrozole was rapid with small individual difference, the tissue distribution of letrozole was more than that in blood, and the clearance was slow. Letrozole was similar to three-compartment model in vivo. Due to metabolism and excretion, the AUCs of letrozole varied greatly among individuals.
Addendum to "D-extending modules" [Hacet. J. Math. Stat. 49(3), 914-920, 2020]

After the paper [1] was published, the following information about D-extending modules was pointed out by Adnan Tercan. Let $r$ be a left exact preradical in the category of right $R$-modules and let $M$ be a right $R$-module. A submodule $N$ of $M$ is called exact in $M$ provided $r(M/N)=0$. A module $M$ is called an ES-module provided every exact submodule of $M$ is a direct summand of $M$. ES-modules was introduced by A. Tercan in [2]. Since socle is left exact preradical, ES-modules coincide with D-extending modules for $r=Soc$.The author who first noticed the ES-module via personal communication with A. Tercan would like to thank him for this reference.

Published: June 2021

Integrasi teknologi, manajemen dan bisnis yang menghasilkan produk yang unggul, inovatif dan kompetitif tidak hanya tergantung pada penguasaan hardskills para pelakunya, namun juga perlu penguasaan softskills termasuk bagi para mahasiswa. Pembekalan softskills bagi mahasiswa menjadi sangat penting supaya mereka tidak hanya memiliki kompetensi akademik dan profesionalitas (hardskills) saja, namun juga kemampuan intrapersonal dan interpersonal (softskills). Kemampuan intrapersonal meliputi kesadaran diri dan kemampuan diri. Sedangkan kemampuan interpersonal meliputi kesadaran sosial dan kemampuan sosial. Pembelajaran softskills mengantarkan peserta didik untuk mengalami perubahan perilaku secara perlahan-lahan sehingga mereka menjalankan, merasakan manfaat yang diperoleh hingga menjadi kebiasaan. Experiential learning merupakan sebuah proses pembelajaran dimana para pembelajar menggabungkan pengetahuan, keterampilan dan nilai melalui pengalaman-pengalaman langsung. Pembelajaran akan lebih optimal apabila para peserta dilibatkan. Ide dan prinsip-prinsip yang dialami dan ditemukan oleh para pembelajar akan lebih efektif dalam perubahan perilaku. Makalah ini memaparkan konsep pengembangan softskills dengan metode experiential learning dan peningkatan peran dosen sebagai fasilitator.
