Başlıkta belirtilen ((E)-2,4-di-tert bütil-6-((4-florofenilimino)metil)fenol (I) ve (E)-2,4-di-tert-bütil-6-((3-iyodo-4-metilfenilimino)metil)fenol (II) Schiff bazlı bileşiklerin hedef protein yapısı olan Kannabinoid Reseptörü 1 (CNR 1) protein yapısı ile Moleküler Docking çalışması yapılmıştır. Ligand yapıları ile hedef protein yapısı birleştirildikten sonra oluşan kovalent bağlar ve kovalent olmayan iyonik bağlar, hidrojen bağları, Van der Waals bağlarının protein yapısının 3-boyutlu (3B) katlanması üzerindeki etkisi tartışılmıştır. Bunlara ek olarak, ilaç adayı bu iki bileşiğin fizikokimyasal özellikleri, lipofilisitesi, farmokinetik özellikleri, sıvı çözünürlükleri, tıbbi kimya ve ilaç benzerliği araştırmaları kuramsal olarak yapılmıştır. Yapılan kuramsal hesaplamalar sonucunda bileşik (I) ve bileşik (II)’nin CNR 1 protein yapısı ile H etkileşimi incelendiğinde aromatik benzen halkasına iyot atomu bağlı olan bileşik (I) protein yapısı alıcı (donör) verici (akseptör) etkileşiminin, benzen halkasına flor bağlı olan bileşik (II)’ye göre daha fazla olduğu sonucuna ulaşılmıştır. Bileşik (I) ve bileşik (II)’nin hedef protein yapısı ile moleküller arası kutuplu yük durumları incelendiğinde, dışarıdan eklenecek yeni moleküle karşı nötr ve kararlı olduğu düşünülmektedir.

Bu çalışmada, gıda endüstrisinde önemli bir yere sahip olan kazein ve glüten fonksiyonel özellikleri bakımından karşılaştırılmıştır. Protein örneklerinde viskozite, iletkenlik, kitle yoğunluğu, Hausner oranı ve Carr indeksi, ıslanabilirlik, su tutma kapasitesi, yağ bağlama kapasitesi, köpük oluşturma kapasitesi ve stabilitesi, renk, emülsiyon aktivitesi ve stabilitesi ve son olarak çözünürlük analizleri gerçekleştirilmiştir. Kazeinin (2.05±0.16 g su/g protein) su tutma kapasitesi glütene (1.64±0.10 g su/g protein) göre daha yüksek bulunmuştur. Glütenin köpük oluşturma kapasitesi kazeinden daha yüksek olduğu, köpük stabilitesin ise glütende 60. dakika sonunda bile aynı düzeyde kaldığı gözlenmiştir. Glütenin emülsiyon stabilitesinin kazeinden daha yüksek olduğu belirlenmiştir. Protein örneklerinin, beklendiği gibi, izoelektronik noktalarda en düşük çözünürlük gösterdiği, yüksek pH değerlerinde ise oldukça yüksek çözünürlük gösterdiği belirlenmiştir. Ayrıca, kazeinin glütene göre daha viskoz çözeltiler oluşturduğu, glütenin ise yüksek pH değerlerinde kazeine göre daha fazla çözündüğü gözlenmiştir. Her iki proteinin de iyi akış özelliği gösterdiği Hausner oranı ve Carr indeksi ile belirlenmiştir. Hausner oranı kazeinde 1.69±0.02 ve glütende 1.86±0.10; Carr indeksi ise kazeinde 40.84±0.85 ve glütende 46.24±1.80 olarak belirlenmiştir. Renk ölçümlerine göre glütenin daha parlak ve açık renk olduğu, kazeinin ise daha yüksek a* ve b* değerlerine sahip olduğu tespit edilmiştir. Elde edilen sonuçların, çalışılan proteinlerin gıda ve farmasötik uygulamalarda kullanımına katkı sağlayabileceği düşünülmektedir.
Investigation Mechanical Properties of Shipbuilding Steel Joined By Submerged Metal Arc Welding And Gas Metal Arc Welding Methods
Authors: SEKBAN Dursun Murat , KILICASLAN Resul
Published: September 2023

Merchant ships are generally built by joining steels with various welding methods. When the welding methods used in shipyards are examined, it is seen that gas metal arc welding (GMAW), submerged arc welding (SAW), covered electrode arc welding and tungsten inert gas (TIG) welding come to the fore. In the assembly of ship hull sheets, GMAW and SAW are generally preferred. In this sense, it is extremely important to characterize the mechanical properties of the weld zone after welding of the shipbuilding steel joined by these two welding methods. When the studies examined, although there are few studies on the joining with GMAW and SAW of shipbuilding steels, no study has been found on the comparative examination of these two welding methods. In this context, within the scope of the study, 3701 shipbuilding steel, which is used extensively in shipbuilding, was joined with SAW and GMAW methods and the hardness, tensile, impact and bending properties of the welding zone were examined comparatively. In consequence of the tests, it was determined that higher mechanical properties were obtained than the base metal in both welding methods. Also, it was found that the welding zone of the shipbuilding steel joint by the SAW method had relatively better mechanical qualities.

Nüfus yoğunluğunun yüksek olduğu şehirlerde raylı sistem (RS) taşımacılığına olan talep sürekli artmaktadır. Artan taleple birlikte bu sistemlerde enerjinin verimli bir şekilde yönetilmesi neredeyse zorunlu hale gelmiştir. Verimli enerji yönetimi hem karbon emisyonlarını hem de işletme maliyetlerini azaltacaktır. Rejeneratif frenleme (RF) ile enerji üretme kabiliyetine sahip RS araçlarda, üretilen RF enerjisinin sisteme en uygun şekilde entegre edilmesi enerji verimliliğine katkı sağlamaktadır. Bu amaçla, bu çalışma RF enerjisi ile desteklenen enerji verimli dinamik sürüş tekniği (EVDST) modelini kullanarak raylı sistemlerde enerjinin verimli bir şekilde yönetilmesini amaçlamaktadır. Modelin optimum tasarımı, RS araçları için yatay kurplu bir hat boyunca boşta çalışma için en uygun hız profillerini ve başlangıç konumlarını seçmeyi ve maksimum enerji verimliliği elde etmeyi amaçlamaktadır. Önerilen model, minimum yolculuk süresi (MYS), minimum çekiş enerjisi tüketimi (MÇET) ve maksimum rejeneratif frenleme enerjisi üretimi (MRFEÜ) gibi tek amaçlı fonksiyonların optimizasyonunu içermektedir. Ayrıca, önerilen model MÇET/MRFEÜ, MÇET/MYS, MRFEÜ/MYS ve MÇET/MRFEÜ/MYS gibi çok amaçlı fonksiyonların optimizasyonunu da kapsamaktadır. Tek amaçlı ve çok amaçlı fonksiyonlar, operasyonel kısıtlamaları ve optimum çalışma bölgelerini keşfetmek için senaryo tabanlı bir şekilde Sürekli Zaman Karınca Kolonisi Optimizasyon Algoritması (ACOR) kullanılarak optimize edilmiştir. Çalışma sonucunda MRFEÜ/MÇET oranında %53,459'luk bir verimlilik elde edilmiştir. Önerilen senaryo tabanlı modelde MÇET için %32,832'lik bir oran elde edilirken, MRFEÜ için %80,060'lık bir oran elde edilmiştir. Gerçekleştirilen çalışma ile literatürdeki sürüş modellerine alternatif olarak kurp yapısının sistem dinamiğine etkisi artırılmış ve daha gerçekçi bir sürüş modeli geliştirilmesi sağlanmıştır. Ayrıca kullanılan yapay zeka optimizasyon tekniği ile literatüre sürüş modeli geliştirilmesi noktasında farklı bir bakış açısı sunarak katkıda bulunmuştur.
Impact of rubber aggregate treatment on the mechanical properties of cement stabilized base course with waste rubber
Authors: Zvonarić Matija
Published: September 2023

The incorporation of waste rubber in cement-stabilized bearing layers exhibits drawbacks, such as a reduction in the mixture's strength. To address these drawbacks, various treatments can be applied to the rubber. This research investigates the treatment of rubber with sodium hydroxide and boiling water. The rubber treated using these methods was incorporated into a mixture defined within the „RubSuPave“ project that did not meet the compressive strength requirements for installation in the pavement's bearing layers. The results indicate that both rubber treatments lead to a decrease in the compressive strength of the mixture. After 7 days, the reduction is similar for both treatments, while better results were achieved after 28 days with the sodium hydroxide treatment. Additionally, after 28 days of curing, the rubber treated with sodium hydroxide exhibited increased stiffness in the stabilization mixture. Furthermore, the rubber surface was analyzed using a scanning electron microscope, revealing significant irregularities caused by both treatments. The applied methods did not result in an increase in the mixture's strength.
Review and application of operational modal analysis methods in the frequency domain
Authors: Pajan Jurica , Duvnjak Ivan , Ereiz Suzana
Published: September 2023

Operational modal analysis (OMA), also known as ambient modal analysis, started its development in the 1990s. Unlike classical experimental modal analysis, it does not require controlled and measured excitation, which makes it practical for use on large structures that are difficult to excite due to their size. Modal parameters can be identified by processing the collected records of the measured quantity in the frequency and time domains, therefore the methods of operational modal analysis can be divided into these two categories. In this paper, the methods developed in the frequency domain are briefly described, and the differences in modal parameters of a bridge superstructure are compared for each method.

Published: September 2023

This paper presents a part of research conducted on prestressed concrete bridges constructed by the balanced cantilever construction method. The bridge structure is described in the introduction. Equipment for continuous strain monitoring as well as eight sensors on concrete and prestressing steel were installed. The bridge was monitored during the entire construction period and for two months after. A numerical model that simulates real structure behavior during and after construction was made, taking into account the time-dependent effects on concrete and prestressing steel. The results of the numerical model are analyzed with and without time-dependent effects and show good overlap with the measured data. It is concluded that the chosen numerical model with time-dependent effects correctly presents real bridge behavior. Material rheology analysis shows a 0.40 MPa difference in stress.
CREATING CUSTOMER-CENTRIC SUPPLY CHAINS: THE 4R AND 4C APPROACHES
Authors: ŞİŞMAN Gülşah
Published: September 2023

Building customer-oriented supply chain is a critical strategy that businesses adopt to gain competitive advantage and increase customer satisfaction. This approach requires focusing on customer demands and needs. The 4R approach (responsiveness, resilience, reliability and realignment) developed to build a customer-oriented supply chain provides a solid foundation for the development of the strategy in this context. Businesses can increase customer satisfaction with the ability to respond to rapidly changing demands. Durability and reliability emphasize the ability of supply chains to cope with unexpected challenges, while business process reorganization increases operational efficiency. Similarly, the 4C approach (coordination, collaboration, capability and connection) developed to create customer-oriented supply chains encourages integration throughout the entire supply chain. Coordination and cooperation between businesses ensures efficient information sharing and resource management. Therefore, it aims to create an efficient and flexible structure by connecting all components of the supply chain.  In this study, 4R and 4C approaches, which are developed to gain competitive advantage and create flexible and efficient supply chains that are compatible with customer needs, will be presented with examples from the literature. These approaches are essential for successful competition in today's dynamic business environment.

AESTHETIC THEORY IN TURKIS MUSIC PERFORMANCE METHODS
Authors: ABAYLI Özcan
Published: September 2023

The issue of what should be the elements that make up the aesthetics in Turkish Music performance methods has not been adequately addressed scientifically. However, Turkish music contains the rich aesthetic accumulation of a deep-rooted cultural heritage that extends to the present day. It is inevitable that the aesthetic elements in the maqam, rhythm and melodic structures of Turkish Music works will make significant contributions to both academic studies and performance. In this context, aesthetics and music philosophy especially in the creation processes of musical works have a special importance. Therefore, the study of aesthetic elements in the genres and forms of Turkish Music repertoire emerges as a compulsory field. The value of aesthetics, which is defined as the way of searching for the beautiful, in Turkish Music works is directly proportional to the compositions of the makams and tempos. In the analysis of a musical work, the form that forms the building blocks of the work is very important. Aesthetic questioning on the form should be made through the elements of motif, sentence, clause and section. However, studying all of the aesthetic elements of Turkish Music, which has a very wide repertoire, requires a lot of effort and time.   In this article, first of all, aesthetic perception, aesthetic attitude, aesthetic pleasure etc. related to aesthetic theory. By emphasizing the main concepts, the aesthetic elements in the performance of Turkish Music works with the aesthetic questioning method, which is one of the most basic elements of creativity, are studied under the headings by giving examples.

GEOGRAPHICAL FEATURES OF SETTLEMENT NAMES IN KONYAALTI (ANTALYA) DISTRICT
Authors: SARI Cemali , ÇAKIR Gamze
Published: September 2023

From ancient times to the present, humans have bestowed meaningful names upon parcels of land where they conduct their daily activities, and the transmission of these names to the present day enables a connection between the past and the present. In this context, when the names of settlements given to land parcels in Anatolia are examined, it can be observed that individuals' cultural characteristics and their lived geography have an influence on nomenclature.   This study aims to classify the urban (15) and rural (24) neighborhood names of the Konyaaltı district based on geographical attributes. In this regard, a qualitative research method was employed, utilizing document analysis as the data collection tool to classify place names. According to the findings, it has been determined that physical geography elements (65%) have a greater impact on the determination of settlement names compared to human geography elements (35%). Place names created based on physical geography elements show a preference for names related to water bodies, whereas place names created based on human geography elements exhibit a preference for names associated with personal names, lineage, and tribal affiliations. The intention is to examine and contribute to Turkish culture by exploring these findings and their implications.
Multithecas: from bookstands to instants
Authors: Saraiva Rodrigues Olira
Published: September 2023

This work is the product of postdoctoral research in Cultural Studies carried out by the Advanced Program of Contemporary Culture (PACC) of the Faculty of Letters of the Federal University of Rio de Janeiro (UFRJ), finalized in 2019. It is a book that reflects one particular research ahead of its time, and the reason is: although it was carried out in 2019, in 2020, the world, facing a pandemic that has not yet ended, sees the emergence of a remote system amid the complexity of the contemporary, which imprints its meanings and maintains the dialogicity with its time, in sociotechnical constructs of access and sharing. In this context, new concepts and practices are summoned, arising from humanity’s historical and collaborative journey towards democratizing knowledge, (re)designing spaces, and expanding strategies.
Mythical Infrastructuring
Authors: Cordero Rodrigo , Mascareño Aldo , Rodríguez Ignacia , Salinas Francisco
Published: September 2023

The very nature of large-scale infrastructure projects—long design and construction periods, high investment, and impact on social and natural spaces—makes them prone to socioecological and technical conflicts. These conflicts materialize in stories that become keystones in the making of infrastructure. In this article, we analyze the infrastructuring power of stories by drawing on the case of the Chacao Bridge on Chiloé Island in southern Chile, a controversial infrastructure project that has been in the making over the last six decades. We argue that the “absence” of the bridge creates a space for the production of stories on the island's inherited past and imagined future that keeps recurring and growing in the form of myths. Thus, we propose the concept of “mythical infrastructuring” to capture this process. We then conclude by arguing that the Chacao Bridge project develops its infrastructuring presence over landscape and culture in contradictory ways that cannot be solved technically or symbolically.

Published: September 2023

OBJECTIVE

Preoperative grading of nonenhancing motor eloquent gliomas is hampered by a lack of specific imaging surrogates. Tumor grading is crucial for the informed consent discussion before tumor resection. In this paper, the authors hypothesized that navigated transcranial magnetic stimulation (nTMS)–derived metrics could provide significant information to distinguish between high- and low-grade motor eloquent gliomas that present as nonenhancing tumors and therefore contribute to improving patient counseling, timing of treatment, preoperative planning, and intraoperative strategies.

METHODS

The authors conducted a retrospective single-center cohort study of patients admitted for tumor surgery between January 2018 and April 2022 with a nonenhancing motor eloquent glioma and preoperative bilateral nTMS mapping. nTMS data including resting motor threshold (RMT), interhemispheric RMT ratio (iRMTr), Cortical Excitability Score (CES), area and volume of cortical activation, and motor evoked potential (MEP) characteristics were obtained and integrated with demographic and clinical data.

RESULTS

Thirty patients met the inclusion criteria, and 10 healthy participants were recruited for comparison. Seizures were the most common presenting symptom (25 patients) and WHO grade 3 the most common tumor grade (21 patients). The area and volume of functional cortical activation of both the abductor pollicis brevis and first dorsal interosseous muscles were decreased in healthy participants compared with patients with WHO grade 3 glioma (p < 0.05). An abnormal iRMTr for the lower limbs (16.7% [1/6] WHO grade 2, 76.2% [16/21] WHO grade 3, 100% [3/3] WHO grade 4; p = 0.015) and a higher CES (maximal abnormal CES: 0% [0/6] WHO grade 2, 38% [8/21] WHO grade 3, 66.7% [2/3] WHO grade 4; p = 0.010) were associated with the prediction of high-grade lesions. A total of 7280 MEPs were analyzed. A significant increase in the amplitude and a significant decrease in latency in the MEPs for the first dorsal interosseous and abductor digiti minimi muscles (p < 0.0001) were identified in healthy participants compared with WHO grade 3 glioma patients.

CONCLUSIONS

Nonenhancing motor eloquent gliomas have a different impact on both anatomical and functional reorganization of motor areas according to their WHO grading.
Spontaneous shrinkage of sporadic vestibular schwannomas: a clinical and radiological analysis
Authors: Daoudi Hannah , Diagon Pierre Le , Alciato Lauranne , Rodallec Mathieu , Nguyen Yann , Kalamarides Michel , Sterkers Olivier , Lahlou Ghizlene
Published: September 2023

OBJECTIVE

The natural history of sporadic vestibular schwannoma (VS) is unpredictable, as tumors may or may not grow and can even spontaneously regress. A spontaneous VS shrinkage MRI-based pattern has been proposed with either a scalloped tumor aspect in the cerebellopontine angle or the appearance of a CSF-filled space surrounding the intracanalicular (IC) tumor within an enlarged canal. The authors of this retrospective study aimed to describe the evolution of sporadic VSs with radiological signs of VS regression and to identify prognostic factors for tumor shrinkage.

METHODS

All MRI scans obtained during patient follow-up were reviewed for extracanalicular (EC) and IC size and tumor characteristics. Volumetric measurements were performed on the first and last MRI scans. Shrinkage was considered to have occurred if the tumor size had decreased by ≥ 2 mm in its largest diameter and/or if the volume had decreased by ≥ 20%. Audiometric data were also collected.

RESULTS

Among 512 patients under observation for sporadic VSs, 66 (13%) had at least one radiological sign of VS regression and 31 of these (6% overall) had confirmed tumor shrinkage. The mean follow-up was 4 ± 2.5 years. One radiological sign was present on initial MRI in 58% of patients and appeared during the follow-up period in the remaining 42%. Two groups were identified: 31 patients (47%) demonstrated progressive tumor regression during follow-up, and tumors in 35 patients (53%) remained stable once signs of regression were identified (assuming a stabilized regression). The prognostic factors for VS regression were as follows: EC VS extension (p = 0.02), cystic lesion (p = 0.002), and central necrosis (p = 0.02). The mean pure-tone average (PTA) was 43 ± 26.2 dB at the time of diagnosis and 53 ± 28.3 dB at the last visit (p < 0.0001). Among patients with an observed tumor shrinkage, ∆PTA was lower if the inner ear signal on the high-resolution T2-weighted image had improved (−3 ± 8.9 dB, n = 11) than if the inner ear signal had not improved (−10 ± 6.9 dB, n = 20) (p = 0.02) between the initial and last MRI scans.

CONCLUSIONS

Spontaneous shrinkage of sporadic VSs could be suspected based on two radiological aspects that are indicative of VSs in progressive or stabilized regression and is an additional argument for the conservative management of these tumors. During follow-up, recovery from a reduced to a normal cochlear fluid MRI signal is a good indicator for hearing preservation.
DIRECTIONS OF ELECTRICITY MARKET REFORMATION
Authors:   KROK University, Tkach Dmytro
Published: September 2023

The article analyzes the current state of reforming of the electricity market of Ukraine, the basis of which is the new electricity market introduced on July 1, 2019. The purpose of the article is to reveal the main factors and trends that affect the reform of the electricity market of Ukraine at the present stage and substantiate proposals for solving the problems of this industry. Ensuring of the development of competition became the key element of the market reform. In addition, Ukraine pledged to the European Union to reform the energy market, that became the reason for the allocation of five hundred million euros of financial assistance. The developed new market has established the following rules. Thus the control of state enterprise “Energymarket” over the production and sale of electricity was eliminated. Instead of one monopolist, two new entities entered the market. The first provided the activities and organization of contracts for the purchase and sale of electricity on the market according to the principle of "day ahead", or on the intraday market that is called market operator. The second one is involved into the purchase of "green" energy from the manufacturer, namely solar and wind, and is called SE "guaranteed buyer". Regional energy supply companies were reorganized into operators of electricity distribution system. On the basis of the existing regional power companies, new enterprises for electricity supply were created, which led to an increase in the number of players on the market after its reformation. At the same time, a wholesale market was created, the segments of which included bilateral contracts, exchange of contracts for physical supply, exchange of financial contracts, as well as the balancing market and the market of additional services. However, it is established that in order to improve the situation with energy sector, the Verkhovna Rada needs to resolve the differences between the Law of Ukraine “On Joint Stock Companies” and the Law of Ukraine “On Management of State-Owned Objects”. Attention should be paid to building of the institutional capacity of State Enterprise Ukrenergo. All this requires from the Verkhovna Rada to adopt such laws that would create optimal conditions for the activities of joint stock companies, call off double taxation, improve the stock market and the capital market. Reformation of the energy sector requires improving of the independence and efficiency of the regulator in this sector. Thus the issue appeared about whether the regulator is able to issue a certificate of NPC Ukrenergo as a body with special responsibilities. And this is a crucial condition for the integration of the Ukrainian energy system into ENTSO-E. That is why the Cabinet of Ministers of Ukraine must create an independent regulator that meets the criteria of the Energy Community.The Ukrainian authorities need to find sources to pay the debt in the electricity market, which will greatly simplify the procedure for its output.
DEVELOPMENT OF MARKETING STRATEGY ON ENTRY OF UKRAINIAN MANUFACTURERS INTO FOREIGN MARKETS
Authors:   KROK University, Tkach Dmytro
Published: September 2023

The article analyzes the problems of development of marketing strategy for Ukrainian manufacturers to enter into foreign markets. It is noted that the marketing strategy of a successful enterprise can not function effectively without the organization of successful sales on foreign markets. In 90s of the twentieth century, a powerful rise in the marketing of foreign trade as an important component of production costs, was initiated. When entering foreign markets, business owners need to know exactly which marketing steps will be profitable and what measures should be implemented to prevent losses. To do this, they need to properly evaluate marketing activities, using appropriate methods and tools of analysis. The aim of the article is to reveal the main factors and trends that influence the formation of the marketing strategy of the Ukrainian producer to enter foreign markets. It is emphasized that in Ukrainian economics there are several approaches to assessing of the effectiveness of the company's marketing policy in entering of foreign markets. Thus, the Ukrainian economist T. Derevianchenko proposed a systematization based on quantitative indicators of productivity assessment. Ukrainian economists V.Verba and O. Grebeshkov expressed the following: “all current methodological approaches to the parameter of the assessment tool should be reduced to two groups: 1) on the basis of expert assessments; 2) on the basis of the formulation of the material price". Regarding the next group of indicators, we will use the approaches expressed in the works of Ukrainian economist P. Savchuk, who says that in the current conditions the price of production as a measure of owner's capital has to be the comprehensive indicator of productive work of the enterprise. Theoretical works of foreign scientists are analyzed. J. Lanskold provided a detailed description of the effectiveness of marketing, based on a study of the indicator of return on marketing. T. Ambler proposed a different gradation of numerical and qualitative marketing features. F. Kotler gave the following definition of marketing strategy - a well-established scheme of marketing steps, through which the company hopes to carry out its marketing objectives. Porter emphasizes the following strategies: low cost, differentiation and consolidation.

Das Einrichten von Naturwaldreservaten ist eine wichtige Massnahme zur Erhaltung und Förderung der Biodiversität im Wald – das gilt besonders für Arten, die auf späte Waldentwicklungsstadien und Totholz angewiesen sind. Im Rahmen des Projekts «Biodiversität und Habitatstrukturen im Wildnispark Zürich Sihlwald» untersuchten wir zwischen 2016 und 2020 vier Organismengruppen (Moose, Flechten, xylobionte Käfer und totholzbewohnende Pilze) auf 69 Probeflächen der kantonalen Stichprobeninventur. Um zu verstehen, wie ihr Vorkommen mit verschiedenen Waldparametern zusammenhängt, verglichen wir Modelle, die auf Inventurdaten basieren, mit solchen, die nur Fernerkundungsdaten verwenden. Während ein etwas stärkerer Zusammenhang der Artenvielfalt totholzbewohnender Pilze mit Inventurdaten (z.B. Totholzvolumen) gefunden wurde, waren es bei den xylobionten Käfern eher Fernerkundungsdaten (z.B. Vegetationshöhe). Bemerkenswert ist, dass der Sihlwald nach knapp 20 Jahren ohne Bewirtschaftung einige Artenhighlights beherbergt, etwa die Zitronengelbe Tramete (Antrodiella citrinella) – der Pilz gilt als sogenannte Urwaldart. Unsere Modelle liefern wertvolle Hinweise darauf, wie zukünftige Biodiversitätsmonitorings mithilfe von Fernerkundung unterstützt werden können. Zudem bilden die erhobenen Daten die Grundlage für ein Langzeitmonitoring der Biodiversität im grössten Naturwaldreservat der Schweiz in der Buchenwaldstufe und ermöglichen in Zukunft Aussagen über die Entwicklung des Waldes zu einem Refugium für Arten, die in bewirtschafteten Wäldern kaum überleben können.

The average value of LVEF and EDI at the time of the control follow-up was significantly different in the PICM group and non-PICM group: 38.6±5.9 vs. 53.5±5.7 % (p<0.001) and 97.90±20.75 vs. 60.90±19.32 ml/m2 (p<0.001). All patients from the study group during follow-up went through protocol echocardiography, at which intraventricular and interventricular asynchrony were examined, the number of left ventricular segments with reduced deformation were fixed, and the global longitudinal deformation of the left ventricle (GLS) was calculated. The values of these parameters differed significantly in the PICM group and non-PICM group: intraventricular asynchrony was 261.1±61.0 vs. 146.1±62.8 ms (p<0.001), interventricular asynchrony 91.0±36.4 vs. 54.2±22.2 ms (p=0.014), the number of segments with reduced deformation 8.1±2.6 vs. 3.91±2.30 (p<0.001), GLS -9.7±2.6 vs. -14.9±3.4 (p<0.001). At the time of the follow-up examination, sensitivity on ventricular lead in the PICM group was significantly reduced compared to patients with preserved LVEF (6.26±4.02 vs. 11.56±3.86 mV; p=0.045). The paced QRS width in the PICM group was significantly greater (163.0±22.7 vs. 150.8±14.5; p=0.046) and there were more patients with rate-adapted cardiac pacing in the PICM group (4 (40 %) vs. 2 (8 %)), p=0.0305).Conclusions. According to the obtained data, cardiomyopathy due to right ventricular pacing develops rather instantaneously in the first years after PM implantation, rather than slowly progressing over time, although a multivariate regression analysis of risk factors for the development of PICM has yet to be performed on the obtained clinical data. Biventri­­­cular paicng effectively eliminates the consequences of non-physiological right ventricular myocardial paicng, improves LV systolic function. Conduction system pacing may potentially reduce the risk of right ventricular pacing-induced cardiomyopathy in patients with preserved LVEF.

Gerhana bulan dapat terjadi ketika bulan menutupi bayangan bumi. Gerhana bulan ini hanya dapat terjadi pada saat posisi Matahari, Bumi dan Bulan berada pada satu garis lurus atau hampir  lurus dan pada saat Bulan sedang dalam fase bulan purnama. Dalam menyikapi peristiwa gerhana bulan, terdapat perbedaan diantara masyarakat. Beberapa mengaitkan gerhana bulan yang terjadi dengan berbagai persepsi yang berkembang di masyarakat mereka. Salah satu tradisi masyarakat suku osing di Banyuwangi saat terjadi gerhana bulan. Masyarakat di sekitar jika mempunyai hewan ternak yang bertelur ataupun tanaman palawija yang sedang mengalami pertumbuhan akan dibangunkan dengan dipukul menggunakan kain, dan wanita yang hamil diwajibkan mandi disungai dengan posisi kepala menghadap ke aliran sungai.

Research on the estimation of bedrock depth in Yabaso village, Jayapura district using the Schlumberger configuration Vertical Electrical Sounding (VES) method and the HVSR method has been carried out. The total observation points are three points where VES is one point and VHSR are two observation points. VES measurements used a set of resistivity meter model AK HV 500 with a maximum spread length of the current electrode is 100 m. HVSR measurements use a portable seismograph set and the measurement time for ambient seismic waves is 60 minutes. VES and HVSR data processing respectively using IPI2Win and Geopsy software. The model parameters resulting from the inversion of the VES data show that there are nine layers with a resistivity range between 18 – 25,260 Ωm. Layer 1 is a heap of sandy gravel with a resistivity value of 92 Ωm. Layers 2 to 7 are part of alluvium formations and coastal deposits (Qa) with resistivity values of 18 – 264 Ωm. While layers 8 and 9 are fragments of weathered ultramafic rock (um) and compact and dry ultramafic rock respectively. The source rock (bedrock) is layer 9 which is at a depth of 42 m. The results of HVSR data processing show that the natural frequencies at the two observation points are very small (<2.5 Hz), namely 0.85 Hz and 0.83 Hz. According to Kanai's classification, this frequency value is type I, class IV, namely alluvial rock. The depths of source rock based on the HVSR method at measurement points 1 and 2 are 43 m and 44 m, respectively. There is agreement in the estimation of the depth of the source rock obtained from the VES and HVSR methods even though the two methods utilize two different physical parameters.

The creation of composite construction materials, which have a less harmful impact on the environment both at the stage of their production and in the process of their use, is of great interest in the global construction industry. Recent innovations have led to the creation of foamed geopolymer concrete or geopolymer foam, which includes the operational advantages of thermal and acoustic insulation materials, saves energy by reducing heat loss, and contributes to the reduction of CO2 emissions into the environment. For a better understanding of the properties and benefits related to the use of foamed geopolymer materials, this paper presents studies of the volumetric mass of these materials obtained from limestone waste and silicate activator. Samples with a ratio of components (limestone waste: activator) of 70:30, 75:25, and 80:20 were obtained. Studies of the volumetric mass depending on changes in the concentration of alkali in the solution of the gas generation activator showed that the minimum values of the volumetric mass are achieved at 1 mol/L concentration of alkali. In addition, it was found that the best foaming geopolymer material is achieved at a ratio of components of 80:20 and at a content of the gas generation activator solution in the mixture of 18% mass.

BACKGROUND: Working part-time or full-time is a persistent dilemma for women, especially mothers, as they strive to manage their time across various roles. However, the existing literature remains unclear on whether part-time work contributes more to life satisfaction than full-time work. OBJECTIVE: This study aims to describe and compare time-use patterns in different occupational roles and levels of life satisfaction among 795 mothers in Brazil who are employed either part-time or full-time. METHODS: Data was collected through an online survey and the snowball technique. Regression and correlation analyses were performed on the data obtained from the following instruments: the Role Checklist for assessing time-use within occupational roles, the Satisfaction with Life Scale, and demographic information. RESULTS: Our analysis revealed no significant differences in life satisfaction between mothers working full-time and those working part-time (t (793)=1.160, p = 0.24). However, life satisfaction scores were positively correlated with the number of occupational roles performed (r = 0.222, p < 0.01), higher family income (P < 0.001), and engagement in social roles such as Friend (r = 0.106, p = 0.003), Hobbyist/Amateur (r = 0.08, p = 0.018), and Caregiver (r = 0.07, p = 0.026). CONCLUSION: While our society places significant emphasis on time spent at work, our findings highlight that life satisfaction extends far beyond the dichotomy of working part-time or full-time. There are deeper dimensions to consider, including the number of occupational roles, family income, and engagement in social roles, which have a more substantial impact on overall life satisfaction.

This study scrutinises the influence of foreign direct investment (FDI) inflows, energy consumption on Information and Communication services (ICTs) in selected economies of South Asia. This research is based on heterogenous and second generation framework of panel data-set from 1999 to 2021. This study used augmented mean group (AMG), mean group (MG), and common correlated effects mean group (CCEMG) assessors, which further promotes the substantial and favourable influence of FDI services, and energy consumption on ICTs. However, the impact of terrorism is insignificant on ICTs in the region of South Asia. The results indicate that economies of these region must embrace investment reform measures in order to draw FDI into the services sector, increase exports of services, and progress towards economic stability.
