Triality Groups Associated with Triple Systems and their Homotope Algebras
Authors: Kamiya Noriaki 
Published: April 2021

Abstract
We introduce the notion of an (α, β, γ) triple system, which generalizes the familiar generalized Jordan triple system related to a construction of simple Lie algebras. We then discuss its realization by considering some bilinear algebras and vice versa. Next, as a new concept, we study triality relations (a triality group and a triality derivation) associated with these triple systems; the relations are a generalization of the automorphisms and derivations of the triple systems. Also, we provide examples of several involutive triple systems with a tripotent element.

Published: April 2021

Abstract
In this paper we introduce some new types of contractive mappings by combining Caristi contraction, Ćirić-quasi contraction and weak contraction in the framework of a metric space. We prove some fixed point theorems for such type of mappings over complete metric spaces with the help of φ-diminishing property. Some examples are given in strengthening the hypothesis of our established theorems.

Published: April 2021

Abstract
The last decade has seen multiple research work on the use of LoRaWAN technology in smart agriculture. In open field storage, monitoring is crucial for increasing the logistics efficiency and improving crop quality. As battery maintenance is expensive in such areas, LoRa is a suitable technology that allows for low-power communications. Within the framework of the research, a prototype has been built for tracking goods in open field storage. The battery lifetime has been analysed through calculations and measurements using LoRa communications. Our findings indicate that although sleeping current has the smallest percentage, it has the greatest effect on increasing the battery life, for longer battery life LoRa node must have a low self-discharge battery, and finally, sensors are the main battery depleting factor on the LoRa node.

Published: April 2021

Abstract
Methyl ester biodiesel was produced from Moringa Oleifera oil and Jatropha Curcas oil with the sole aim of assessing the feasibility of the feedstocks as viable sources of biodiesel in Botswana. Oil extraction and transesterification were carried out under identical experimental conditions for both Jatropha Curcas and Moringa Oleifera biomass. Oil was extracted from seeds through a soxhlet extraction method using the solvent, n-hexane. The extracted oil was then trans-esterified at 60 °C using a methanol/oil ratio of 12:1 at a stirring rate of 350 rpm, 3 wt. % catalyst loading and 120 min reaction time. Zinc Oxide modified with fly ash was used as heterogeneous catalyst for the process. GC analysis results of biodiesels produced indicated that the highest biodiesel yield was obtained from Jatropha seed oil. Moringa biodiesel showed a greater proportion of docosanedioic acid while Jatropha biodiesel composed of oleic acid in larger proportions. Both oleic and docosanedioic acid are unsaturated methyl esters. The results obtained suggests Jatropha as the more suitable feedstock as compared to Moringa.

Published: April 2021

Background. Management of multiple gestation complicated by the foeto-foetal transfusion syndrome is among most intricate modern obstetric issues. The syndrome develops in 10–20% of monochorionic diamniotic twins leading to 80–100% mortality in one or both twins if left uncorrected, especially in early syndrome cases. Although foeto-foetal transfusion usually develops with monochorionic placentae, there are notable exceptions of vascular placental anastomoses reported with dichorionic monozygotic twins. The disease supposedly entails from an imbalanced blood interflow between dichorionic twins due to placental vascular anastomoses.Clinical Case Description. Patient S., 32 yo, visited perinatal diagnostics at the Territorial Perinatal Centre of the Children’s Territorial Clinical Hospital with a preliminary diagnosis: 22 weeks and 5 days’ pregnancy. Dichorionic diamniotic twins. Threat of extremely preterm birth. Two caesarean uterine scars. Gestational diabetes mellitus.Medical files: patient history, pregnancy calendar. Pregnancy was regularly monitored with main ultrasound foetometry, foeto-foetal transfusion dynamics control and Doppler velocimetry.Ultrasonographic signs of abnormal haemodynamics underlying the foeto-foetal transfusion syndrome were detected at the first scan at 11–13 weeks 6 days’ term as collar space thickening in one foetus. Hydramnios in one foetus and oligohydramnios in the other were diagnosed at 28 weeks’ gestation conclusively indicating the foeto-foetal transfusion syndrome. This evidence suggested the formation of placental anastomoses, which was confirmed morphologically in placenta examination.Conclusion. A timely diagnosis and correction of emerging complications allowed prolongation of pregnancy in hospital conditions to 33–34 weeks. Both boys were live-born with Apgar score 7–8.

Published: April 2021

Background. Imbalanced pro- and anti-inflammatory systems can unfavourably condition carrying of pregnancy and provoke gestation complications, such as premature rupture of membranes.Objectives. Assessing the contribution of SNP variants -137G>C (rs187238), -607G>T (rs1946518) and -656A>C (rs5744228) of the IL-18 gene promoter to the incidence of extremely preterm premature rupture of membranes.Methods. A case-control study enrolled 120 pregnant women managed at the Perinatal Centre. The women were divided in two cohorts. The study cohort comprised 80 women with premature rupture of membranes at 22–27 weeks 6 days’ gestation hospitalised in a high-risk pregnancy unit, a control cohort consisted of 40 women with physiological pregnancy at 22–27 weeks 6 days’ gestation following outpatient counselling. The cohorts had comparable obstetric and gynaecological histories. The study exclusion criteria were: multiple gestation, foetal chromosomal anomalies, congenital foetal malformations, pregnancy due to assisted reproduction. Genotyping was performed at positions -137G>C, -607G>T and -656A>C of the IL-18 gene promoter with determining a peripheral blood IL-18 level in cohorts.Results. The premature rupture of membranes cohort had a statistically higher serum interleukin-18 concentration compared to control (p = 0.001). Genotyping of the IL-18 gene promoter revealed a statistically higher rate of homozygous -137G>C mutation (CC genotype) in the premature rupture of membranes cohort at 22–27 weeks 6 days’ term (p <0.001), 67 vs. 27% in control.Conclusion. A homozygous IL-18 -137G>C polymorphic variant associated with elevated blood IL-18 levels is statistically more common in pregnant women having premature rupture of membranes at 22–27 weeks 6 days’ gestation.

Published: April 2021

Background. The main hay fever agent in Krasnodar Krai is ragweed pollen (Ambrosia gen.). An important alerting guide for medical practitioners and allergic citizens is the seasonal anthetic calendar and pollen peak times.Objectives. Obtaining of relevant data on ragweed pollen air contamination rate in Krasnodar in a three-year-dynamics (2018–2020) to estimate the anthetic activity correlation with abiotic and anthropogenic factors and the role of pollen indicators in allergic morbidity.Methods. We surveyed the daily average ragweed pollen values in Krasnodar air. Allergic medical visits were analysed in terms of the ragweed anthetic activity and pollen air contamination of the city.Results. A maximal daily average ragweed pollen peak occurs in August: 663.35 p.g./m3 in 2018, 209.89 p.g./m3 in 2019, 80.62 p.g./m3 in 2020. Numbers of medical visits for pollinosis per a selected municipal medical facility: 314 in 2018, 335 in 2019 and 146 in 2020, with a peak period in September--October. Analyses of the air pollution impact on ragweed pollen production revealed a correlation between the pollen rate and values of CO (correlation coefficient r-0.356), NH3 (r-0.198) and dust pollution (r-0.361) in July, August, September and October 2018–2020.Conclusion. Analyses of climatic factors uncovered clear patterns: strongest anthesis corresponds to minimal humidity (<60%), the pollen grain content diminishes with lower humidities dropping to minimal with precipitations and increases at temperatures 20 °C and above. No significant dependency was observed between air pollution and the allergic pollen content. Anthesis in ragweed moderately correlates with the rate of medical visits.
Osteosarcoma of the temporal bone occurring 40 years after radiotherapy: A technical case report presenting en bloc resection of intra- and extracranial lesions followed by a one-stage reconstruction

Published: April 2021

Background:
Osteosarcoma (OS) is a malignant tumor of the bone, which rarely occurs in the head-and-neck regions as a primary or a secondary malignancy. Adequate surgical resection is currently the mainstay of treatment for head-and-neck OS; however, en bloc resection and reconstruction can be difficult because the anatomies of these regions are complex. We present a case of an OS arising from the temporal bone 40 years after radiation therapy, which was successfully treated with en bloc resection and a one-stage reconstruction using intraoperative tissue expansion technique.

Case Description:
A 62-year-old woman who underwent surgery and radiotherapy for a left temporal lesion 40 years before presentation was hospitalized for aphasia and a right hemiparesis. She had a 4 × 3 cm subcutaneous mass in the left temporal area of the head. Computed tomography imaging showed destruction of the left temporal bone and a partially calcified mass. Magnetic resonance imaging showed an enhancing mass with intracranial and extracranial cystic components (5 cm and 3 cm in diameter, respectively). Due to rapid growth of the lesion, a semi-urgent surgery was performed. In this operation, a continuous narrow craniectomy was performed around the tumor using a ruler. Then, en bloc resection of the tumor, with adjacent skin, temporal muscle, skull, dura mater, and cerebral cortex, was achieved. Subsequently, a one-stage reconstruction of the dura mater, skull, and skin of the head was performed using fascia lata, artificial bone, and a local skin flap combined with intraoperative tissue expansion using a 20-French Foley catheter. Postoperative histological examinations revealed the tumor to be an OS.

Conclusion:
We have presented a rare case of an OS occurring from the temporal bone 40 years after radiation therapy. We describe our experience and the surgical methods in this case to provide options for surgical strategies in patients with head-and-neck OS.

Published: April 2021

Aim. Purpose of the study. To study the clinical and functional features of the parameters of arterial stiffness in the elderly, depending on gender differences.
Materials and methods. The study included 497 therapeutic patients aged from 60 to 74 years. The average age of the examined patients was 65.13.9 years. All patients underwent a comprehensive clinical and instrumental examination. The study of the parameters of arterial stiffness and central arterial pressure (BP) was carried out on the AngioScan-01 apparatus (AngioScan-Electronics, Russia). Depending on the sex differences, the entire sample was divided into two age-matched groups: women (n=287) and men (n=210).
Results. In the group of women, systolic levels (13820 mm Hg vs 13419 mm Hg; p=0.018), central (13720 mm Hg vs 13319 mm Hg; p=0.024), average (469 mm Hg vs 456 mm Hg; p=0.018), pulse BP (5316 mm Hg vs 5014 mm Hg; p=0.038), the value of the double product (107.423.5 conventional units vs 101.422.5 conventional units; p=0.004), augmentation index (AI) [22.1 (13.5, 31,3)% vs 15.9 (8.8; 24.9)%; p=0.005], the increase index at a pulse frequency of 75 per minute [23.2 (16.0; 30.5)% vs 15.9 (9.2; 23.5)%; p=0.005] and systole duration in percent (35.505.60 vs 34.244.53; p=0.007) were significantly higher than in the group of men. In addition, men showed a statistically significant increase in the average value of the alternative stiffness index (9.762.61 vs 8.172.03; p=0.005) and the dependence of the AI on age (p0.05). At the same time, a statistically more significant correlation of central and peripheral hemodynamic parameters with the presence of elevated AI (p0.05) was recorded in the group of women.
Conclusion. In older women, an increase in systolic, central, average, pulse BP is associated with an increase in AI and an increase in the magnitude of the double product. In the group of elderly men, the increase in the alternative vascular stiffness index contributes to an increase in the duration of the pulse wave. Statistically more pronounced correlation relationships between the value of the AI and clinical and hemodynamic parameters were recorded in elderly women.

Published: April 2021

Realizar estudios sobre centros históricos implica hacerse cargo de retos teóricos, históricos y prácticos que dependen de la ciudad objeto de estudio. Acotar correctamente el concepto de centro histórico, entender las dinámicas que lo han transformado con el tiempo y la dificultad para acceder a la información existente, hacen de este tipo de estudios una entrada a nuevas metodologías de análisis y recolección de información para entender las ciudades contemporáneas y sus centros históricos. Tunja tiene un centro histórico valioso, posee importantes edificaciones de los siglos XVI y XVII en muy buen estado, testigos de las transformaciones que ha tenido la arquitectura y el urbanismo durante los últimos quinientos años. Sin embargo, la información que se encuentra es fragmentada y desactualizada. Este artículo presenta la metodología usada para recolectar y organizar datos del centro histórico de Tunja, haciendo énfasis en información urbana y arquitectónica para inventariar lo existente al tiempo que se rastrean las transformaciones sufridas a lo largo del tiempo. También se busca determinar la forma en que la normativa actual influye en estas transformaciones, y cómo la arquitectura contemporánea se adapta para insertarse dentro del tejido histórico, afectando su contexto, pero sin detener las dinámicas propias del centro.

Authors: Masum Syed Hasan Imam Al , Arsalan Ali Jacob 
Published: April 2021

Background and Objectives: Thyroglossal duct cyst (TDC) is considered to be the most common congenital neck swelling in children. But its diagnosis can sometimes be challenging, because of abnormal presentation or associated infection. The aim of the present study is to describe the clinical features, anatomical location and management given to these children in the context of Bangladesh.
Methods: This retrospective review of the past 7 years' (between June 2008 and July 2015) records of all children with a histopathologically confirmed diagnosis of TDC was done at the Department of Pediatric Otolaryngology, Dhaka Shisu Hospital, Sher-e-Bangla Nagar, Dhaka. Thirty patients fulfilled the predefined eligibility criteria and were included in the study. Preoperative evaluation consisted of physical examination with regard to movement of the mass with protrusion of the tongue and ultrasonographic assessment of the mass. All the patients were operated by Sistrunk's approach and outcome was assessed in terms uneventful cure, infection and recurrence.
Result: In the present study the children presented with TDC were on an average 7.1 (range: 3.5 - 11 years) years old and were predominantly girls (60%). Majority of patients belonged to middleclass (70%). Urban and rural representations were almost equal. Half of the patients were diagnosed between 5 - 10 years of age. Majority (80%) of the TDCs were located in infrahyoid region just lateral to the midline, 16.7% were located close to the hyoid bone (juxtahyoid) and 3.3% to the suprahyoid region in the midline. All the 30 cases presented with painless cystic swelling which moved upwards with protrusion of tongue. No signs of infection or associated diseases (myxoedema or thyroglossal fistula) were present. An anechoeic character with absence of fluid level was detected with ultrasono imaging of the mass.
Conclusion: Clinical presentation and anatomical location and management were almost same as elsewhere in the world. But in the absence of a complete database including the follow up data, it is not feasible to plan for further improvement of the children with TDC.

Background: This study employed three surgical techniques: total arch replacement (TAR) with frozen elephant trunk (FET), aortic balloon occlusion technique (ABO) and hybrid aortic arch repair (HAR) on patients with type I aortic dissection in Fuwai Hospital, aiming to compare the early outcomes of these surgical armamentariums.Methods: From January 2016 to December 2018, an overall 633 patients (431 of TAR+FET, 122 of HAR, and 80 of ABO) with type I aortic dissection were included in the study. Thirty-day mortality, stroke, paraplegia, re-exploration for bleeding, and renal replacement therapy were compared using the matching weight method (MWM).Results: After MWM process, the baseline characteristics were comparable among three TAR groups. It showed that ABO group had the longest cardiopulmonary bypass (p &lt; 0.001) and aortic cross-clamp time (p &lt; 0.001), while the operation time was longest in the HAR group (p = 0.039). There was no significant difference in 30-day mortality among groups (p = 0.783). Furthermore, the incidence of stroke (p = 0.679), paraplegia (p = 0.104), re-exploration for bleeding (p = 0.313), and CRRT (p = 0.834) demonstrated no significant difference. Of note, no significant differences were found regarding these outcomes even before using MWM.Conclusions: Based on the early outcomes, the three TAR approaches were equally applicable to type I aortic dissection. We may choose the specific procedure relatively flexibly according to patient status and surgeon's expertise. Importantly, long-term investigations are warranted to determine whether above approaches remain to be of equivalent efficacy and safety.
