Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a temporary management modality for non-compressible torso haemorrhage that can be deployed in the pre- and intrahospital setting. This study aimed to compare outcomes following balloon placement in the three aortic zones.

Methods: This is a retrospective study using data from the ABO Trauma Registry. Relevant entries from January 2014 to December 2019 were used and stratified into three groups: those who received Zone 1, 2, or 3 balloon placements.

Results: The study sample consisted of 237 patients: 63 (27%) women and 174 (73%) men, median age 35 years. The primary location of the REBOA balloon was in Zone 1 for 180 patients, while it was nine in Zone 2 and 48 in Zone 3. Complication rates and total durations did not differ significantly between inflation zones. Emergency department mortality rates for Zones 1 and 2 patients were significantly higher than for Zone 3 (P = 0.04), but there was no difference between groups in 24-hour and 30-day mortality rates.

Conclusions: REBOA is currently used in the emergency setting for temporary stabilisation of the bleeding patient. In this cohort, balloon placement occurred in all zones of the aorta for similar durations, with no difference in complication rates between zones. Inadvertent Zone 2 placement was not found to be associated with increased complication rates.

AbstractBatik plays an important role in Indonesia's national identity as a unique tradition. Therefore, it is important to introduce batik to children from an early age to preserve this cultural heritage. This study aims to identify how to introduce batik as a cultural learning tool for children and to understand the cultural elements, community participation, and supporting factors/barriers in introducing batik. This is a descriptive-qualitative study involving batik introducers, managers, guides, and young children. Data were collected through observation, interviews, and documentation, and then analyzed through data reduction, presentation, verification, and validation through triangulation. The results showed that introducing batik requires careful planning, implementation, and evaluation. Batik encompasses six universal cultural elements and involves the community in preserving local culture sustainability. The activity was positively received by children and supported by parents, comfortable and safe locations, adequate facilities, and friendly communities. However, some participants arrived late due to pandemic restrictions, and only a few children from each village were able to participate.Keywords: Batik; Early Childhood; Learning Media; Local CultureAbstrakBatik memainkan peran penting dalam identitas nasional Indonesia sebagai tradisi khasnya.

Determination of impurities in Ta- and Nb-based materials is a necessary operation in supporting technological processes. The existing approaches involve the transfer of a sample into a solution with subsequent isolation of impurities. This procedure is rather complicated and takes a lot of time. For this reason, it is of interest to study the possibilities of direct analysis of solid-phase samples of materials, e.g., X-ray fluorescence analysis (XRF). The usual scheme of X-ray fluorescence analysis, which involves the experimental construction of calibration characteristics for each element to be determined, requires using a large number of reference samples containing a rather wide range of impurities. We present the results of preliminary characterization of samples of technical-grade tantalum and niobium and products on their base. It is shown that for starting materials, only a significant absence of impurities can be determined using XPA, but even for sintered niobium hydride and Ta powder, XPA can be used as a method for rapid assessment of the composition. A SPECTROSCAN MAX GVM crystal-diffraction spectrometer can be used for analysis and a standard software that implements the fundamental parameter method (FPA) can be used for calibration. In this case, the obtained values of the content of impurities may differ by 1 – 2 orders of magnitude from the reference values. However, such an accuracy is often enough to correct technological processes. The limits of detecting impurities by XRF in Ta- and Nb-based materials are revealed: for elements determined by K-series (from Ti to Co), the detection limits lie in the range from 30 to 60 ppm, whereas for the elements determined by M-series (Ta) the detection limit is approximately 200 ppm and for L-series (Nb) the detection limit is in the range from 100 to 150 ppm.

The impact of residual stresses in a DN850 pipe (steel 10GN2MFA) with austenitic cladding, welding stresses in the mounting annular seam of the pipeline, and residual stresses arising in a curvilinear branch DN350 (steel 08Kh18N10T) during manufacture by plastic deformation on the opening and stability of through cracks is considered. Calculations of residual stresses are performed using the finite element method (FEM). It is shown that residual stresses cause a change in the size and shape of the outflow channel, the coolant flow rate, and the value of the J-integral at the crack tip. In case of short cracks and relatively low operating stresses, the crack edges can close on the inside of the pipe wall due to the action of residual stresses thus leading to a decrease or cessation of the leak. A reversed effect of residual stresses on extended cracks is observed at rather high operating stresses: change in the shape of the outflow channel (an increase in the opening of the crack edges on the outer surface of the pipe) leads to a decrease in the friction of the coolant flow against the crack edges and, hence, to an increase in the leak volume. The results of testing full-scale models of elements of a straight section of the pipeline with a welded seam and a curvilinear branch DN350 with artificially created defects by internal pressure and bending moment are presented. It is shown that local through cracks develop from initial defects, which remain stable at maximum design loads (normal operating conditions plus maximum design earthquake) which matches the calculation results and meets the requirements of the applicability of the concept of «leak before break».

A high-strength aluminum alloy 1933 being distinguished by good physicomechanical properties and high manufacturability is widely used in the most critical power aircraft structures, e.g., in a modern AN-148 SSJ aircraft. The alloy is used in production of various parts of articulated joints, thus making study of the durability of the alloy in a complex stress state a relevant goal. We present the results of static and dynamic tests of structurally similar samples (of two types) manufactured according to serial technology and corresponding to the shape of real eyelets of the airframe slats. Preliminary fatigue tests of standard samples (a strip with a hole) were performed to obtain the refined characteristics of the alloy in the T3 state. To analyze the mechanical behavior of the alloy with a different amplitude-frequency character of loading, the asymmetry of the loading cycle (R = 0.1; 0.2; 0.5; 0.6; 0.76; 0.82) and exposure frequencies (10, 60, and 100 Hz) were varied. In is shown that an increase in the average stress of the loading cycle reduced the number of cycles before the destruction of the eyelets: a 2-fold increase in the average stress resulted in a drop in fatigue life by two orders of magnitude (for an amplitude of 5 kg/mm2).

Published: June 2023

COVID-19 pandemic lockdown measures reasonably limited the social contacts of people in many countries. It is crucial to understand the effect of such policies on people’s social ties and the possible need for evidence-based public policy amendments. Therefore, this study examines 1) the prevalence of loneliness in the population aged 15+ in Lithuania in late 2021 and 2) the self-rated effect of the COVID crisis on loneliness in population groups with different levels of loneliness. It also focuses on the socio-demographic characteristics of these population groups. Data from a representative cross-sectional quantitative survey (N = 1067), carried out in November–December 2021, was used. Based on the 6-item De Jong Gierveld Loneliness Scale, descriptive statistics analysis revealed the high prevalence (51% of a medium level of loneliness) in the Lithuanian population. One in three people (36%) declared low-level loneliness, and each seventh or eighth (13%) reported high-level loneliness. The feelings of respondents who reported a high level of loneliness were also less stable; they more often stated that their feelings of loneliness increased during the pandemic. These research findings make contributions to studies of loneliness within the context of sudden crises. They emphasise the importance of policymakers focusing on additional measures when preparing for future emergencies and providing special attention to residents who experience the highest levels of loneliness. Doi: 10.28991/ESJ-2023-SPER-020 Full Text: PDF

In this study, we aimed to determine the nematode diversity in soils from olive orchards in İzmir, Manisa, Çanakkale, and Balıkesir provinces. For this purpose, a survey was carried out in 2021-2022; in each orchard, soil samples were collected from 0-60 cm depth, and nematodes were extracted from collected soils by the modified Baermann Funnel method. Thirty-seven genera of nematodes (Achromodora, Acrobeles, Acrobeloides, Alaimus, Aphelenchus, Aphelenchoides, Boleodorus, Cephalobus, Clarkus, Coslenchus, Ditylenchus, Dorylaimus, Eucephalobus, Filenchus, Geocenamus, Hemicriconemoides, Helicotylenchus, Labronema, Lelenchus, Longidorus, Mesocriconema, Mesodorylaimus, Mesorhabditis, Monhystera, Panagrolaimus, Paratylenchus, Pratylenchus, Pratylenchoides, Psilenchus, Rhabditis, Rotylenchulus, Rotylenchus, Saurtylenchus, Tripyla, Tylenchorhynchus, Tylenchus, Xiphinema) from 21 families were identified in olive-growing areas. According to feeding habitats, nematodes were classified as plant parasitic (19 genera and one plant-parasitic species from fungivore Ditylenchus genera), bacterivores (11 genera), fungivores (3 genera), omnivores (2 genera), and predators (2 genera). Plant-parasitic 27 nematode species (İzmir: 19; Manisa: 16; Balıkesir 15; Çanakkale: 11) were found in soils. The virus vector Longidorus elongatus was among the identified important species. The prevalent plant-parasitic species were Geocenamus brevidens (32%), Filenchus thornei (23%), Helicotylenchus digonicus (29%), while the free-living nematodes were Acrobeloides spp. (100%), Aphelenchus sp. (95.3 %), Cephalobus spp. (97%), and Mesodorylaimus (91.2%). Within bacterivore nematodes, at least one species from the Cephalobidae family was determined in all soil samples.

Today, among renewable energy sources, wind energy is used effectively as a clean and sustainable energy source in electricity generation. The uncertain nature of renewable energy sources and the smart ability of the neural network approach to process complex time series inputs have allowed the use of artificial neural network (ANN) methods in the prediction of renewable energy generation. In this study, the speed and power of wind turbines and electricity generation were estimated from wind speed data using artificial neural networks. In our calculations, the real wind speed data were used in the test phase, and the speed-power data of six different types of wind turbines were used in the training phase. It has been shown that the predictions made by our ANN model from the regression curves of the training, validation, and test data obtained are quite successful and reliable. According to our results, it has been understood that the wind potential of our selected region is good enough and that the electrical energy need for this region can be met from wind energy by using the appropriate wind turbine type, so it is quite appropriate to invest in wind energy.

Bu makalede, değişken bir çıkış gerilimi ve kademeli olarak değişen bir çıkış frekansı elde etmek için tek fazlı matris dönüştürücü ile birlikte Z-kaynak ağı kullanılan bir alternatif akım-alternatif akım (AA-AA) dönüştürücü yapısı incelenmiştir. Bu dönüştürücü yapısında, çıkış gerilimi ve frekansı hem düşürülebilmekte hem de yükseltilebilmektedir. Matris dönüştürücü, doğrudan AA-AA dönüşüm yaparken anahtarlama stratejisi ile çıkış frekansını kademeli olarak değiştirme imkânı sağlamaktadır. Ayrıca, doğrudan AA-AA dönüştürme özelliği sayesinde, geleneksel dönüştürücülerde kullanılan büyük bir DA bağlantı kondansatörüne olan ihtiyacı ortadan kaldırmıştır. Böylece sistem hem daha az maliyetli hem de daha az karmaşık bir yapıya sahip olmaktadır. Bu çalışmada, çeşitli uygulamalarda farklı hız değerlerini elde etmek için kullanılan tek fazlı asenkron motoru sürmek için tek fazlı Z-kaynaklı matris dönüştürücü kullanılmıştır. Bu yapı, asenkron motorun başlatılmasında veya kademeli bir hıza ihtiyaç duyan asenkron motorun hız kontrolünde kullanılabilmektedir. Tek fazlı Z-kaynaklı matris dönüştürücü MATLAB/Simulink ortamında modellenerek simülasyonu yapılmış ve farklı frekans değerleri için simülasyon sonuçları hem direnç-bobin (RL) yükü için hem de tek fazlı asenkron motor için sunulmuştur. Dönüştürücü akım ve geriliminin harmonik spektrumu da incelenerek, harmonik bozulma değerleri farklı frekanslar için verilmiştir.

Tamamen ikili değerlendirmeye dayanan bir matematiksel modelleme olan klasik mantıkta her değer için sadece iki durum vardır, 1 sembolünün verildiği ve doğru anlamına gelen ilk durum ile 0 sembolünün verildiği ve yanlış anlamına gelen ikinci durum. Ancak gerçek bundan daha geniştir ve yalnızca 0 ve 1 olmak üzere iki duruma bağlı olmayabilir. Bu nedenle, yaklaşık veya spesifik olmayan bilgileri temsil etme problemini çözmek için genel çerçeveyi sağlayan yeni bir mantığa ihtiyaç duyulmuştur. Bulanık mantık adı verilen bu mantık ilk olarak 1965 yılında İranlı bilim adamı Lutfi Zadeh, tarafından ortaya atılmıştır. Bulanık mantık, sıcak, soğuk, ılık, az, çok, gibi deyimler ve belirsiz ifadeler aracılığıyla tümdengelim üzerine kuruludur.

Granit Garba is one of the basements that make up the Garba Hills. Research on granitoid rocks that make up Granit Garba was carried out in the village of Tanjung Beringin and its surroundings, Muaradua District, South OKU Regency, South Sumatra Province. The formation of Granit Garba occurs due to the double subduction between Meso – Tethys with Woyla Arc and West Sumatra Block. The complete subduction of the Meso-Tethys plate then caused the collision between the two plates. The characteristics and tectonic evolution of the granitoid rocks were analyzed by conducting an XRF geochemical analysis of the major elements. The results of the analysis of the major elements of granitoid rocks have SiO2 content values ​​ranging from 63.71% to 69.55% it showing that Granit Garba is composed of quartz monzonite and granodiorite. The magma affinity of the two rocks is included in the calc-alkaline series with alumina saturation levels in the form of peraluminous and showing I-type granite.

Kajian Geoteknik Bawah Permukaan Dengan Menggunakan Pendekatan Metode Geofisika
Authors: Narotama Sarjan Achmad Fajar , Muchtaranda Ismail Hoesain
Published: June 2023

Geofisika merupakan studi yang mengkaji kondisi bawah permukaan Bumi berdasarkan parameter fisiknya. Komponen penyusun Bumi masing-masing memiliki ciri fisik yang unik misalnya: kerapatan, kecepatan rambat, konduktivitas listrik, suseptibilitas magnetik, dan konstanta dielektrik dari tiap jenis batuan akan berbeda. Penggunaan metode geofisika telah meningkat secara drastis dalam 50 tahun ini untuk digunakan dalam pelaksanaan eksplorasi sumber daya mineral dan alam. Selain itu, studi geofisika juga dapat berguna dalam membuat evaluasi untuk penilaian stabilitas, perencanaan dan pemantauan infrastruktur yang terdapat dalam bidang Teknik Sipil. Berbagai pendekatan geofisika dapat memberikan informasi penting di lapangan, seperti sifat massa batuan dan anomali strukturnya. Keunggulan dari metode geofisika adalah memungkinkan pengumpulan data di area yang luas yang tidak dapat dieksplorasi secara langsung karena keterbatasan alat maupun biaya, sedangkan kekurangannya adalah data yang dihasilkan tidak unik. Dengan demikian, interpretasi data geofisika harus dibatasi dan divalidasi menggunakan metode eksplorasi langsung maupun uji laboratorium untuk memperoleh hasil yang akurat. Penggunaan geofisika dalam masalah rekayasa geoteknik dikenal sebagai geofisika geoteknik; investigasi ini biasanya mencakup kedalaman total kurang dari beberapa ratus kaki, meskipun terkadang mencapai ribuan kaki. Studi ini mengkaji penerapan metode geofisika yang dapat digunakan untuk membantu pekerjaan geoteknik khususnya dalam pencitraan kondisi bawah permukaan.

Authors:   Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Periyakulam, R Chitra
Published: June 2023

Mentha is a commercially important herbal spice belonging to the
family Labiatae (Lamiaceae). The evergreen herb (foliage) yields essential
oil in distillation containing a large mixture of aroma-chemicals in varying
compositions. As, the mint leaf is vitally used in our culinary preparations,
there is a need to improve the herbage yield and optimize the usage of
organic inputs for leaf production. Hence, the trial was taken to
investigate the effect of organic manures (FYM, neem cake,
vermicompost, biocompost) and biostimulants (Panchagavya and humic
acid) on the growth and herbage yield of mint at the Department of Spices
and Plantation Crops, Horticultural College & Research Institute, Tamil
Nadu Agricultural University, Periyakulam. The highest plant height of
35.22 cm was recorded in plants applied with 50% N as FYM + 25% N as
Vermicompost + 25% N as Neem cake + 3% Panchagavya as foliar spray
(T5). The more number of branches per plant of 25.67 was recorded in the
plants which received 50% N as FYM + 25% N as Vermicompost + 25% N
as Neem cake + 3% Panchagavya as foliar spray (T5). The highest herbage
yield of 7.68 tons per hectare and essential oil content (0.37%) were
recorded in the plants raised in the soil supplemented with 50% N as FYM
+ 25% N as Vermicompost + 25% N as Neem cake + Panchakavya (3%)
as foliar spray (T5). In mint cultivation, the application of organic nutrients
and inorganic fertilizers is commonly practiced to increase the herbage
yield and quality of leaves. In view of the world demand for organic food,
the enhancement of soil health, productivity, and the accessibility of local
resources, cultivation under organic farming can be expected.

Science teachers could play a vital role in promoting health literacy and safe behaviors to limit the spread of communicable diseases. However, there is limited research concerning their attitudes and behavioral intentions toward diseases, such as COVID-19. Using the theory of planned behavior as a framework, we employed a non-experimental survey to compare the behavioral intentions towards adopting COVID-19 preventative measures among pre-service science teachers from South African (n=87) and Indonesian (n=93) universities. Data were collect data using a closed-ended questionnaire. Results show that the behavioral intentions toward COVID-19 between South African and Indonesian pre-service science teachers are similar. Safe attitudes, subjective norms, perceived behavioral control, behavioral, and normative beliefs that support safe behavioral intentions toward COVID-19 were reported, even though vaccine hesitancy may occur. We extrapolate that interventions should be implemented to enhance pre-service teachers’ behavioral intentions and enhance their role in health education.

Published: June 2023

Introduction: Polypharmacy can lead to drug-drug interactions. The aim of this study was to determine the possible factors affecting the prevalence and clinical importance, and interrater reliability of clinical significance of drug interactions in geriatric outpatients. Materials and Method: Potential drug-drug interactions in 228 patients treated in an outpatient geriatric clinic were evaluated in this cross-sectional, retrospective study. The potential significance of the interactions was reviewed separately by a geriatrician and a clinical pharmacist. Results: A total of 1342 drugs were prescribed (median 6 [2-14], per patient). Mean age of the patients was 78±0.5 (65-96). Polypharmacy was present in 64.0% of the patients. A weak positive correlation was found between patient age and the number of drugs used (Rs =.205; p=.002). No drug interaction was detected in 18.0% of the patients. In the prescriptions of the remaining 187 patients 760 category C, 70 category D, and 18 category X interactions (Lexicomp®) were detected. A strong positive correlation was found between the number of drugs per patient and the number of drug interactions (Rs =.734; p<.001). There was a strong correlation between the number of interactions and the presence of polypharmacy (rpb=.702, p<.001). The measure of agreement between the clinicians was more pronounced for category D and X interactions (Cohen’s k=.714 and 1, p<.001). Conclusion: Advanced age, a higher frequency of concomitant use of drugs, and polypharmacy are factors that require clinicians to be aware of drug-drug interactions. Clinical pharmacists can work with geriatricians in outpatient clinics to prevent drug interactions. Keywords: Drug Interactions; Polypharmacy; Health Services for the Aged; Pharmacist.
