La ferrita de hierro-ytrio Y3Fe5O12 (YIG) es un cerámico ferrimagnético con una magnetización de saturación alrededor de 26 emu/g, cuyas propiedades la hacen útil en aplicaciones de microondas. El YIG presenta bajas pérdidas dieléctricas (tan ó) y alta permitividad relativa o constante dieléctrica (Er). La introducción de Bi3+ en el YIG modifica las propiedades magnéticas y disminuye la temperatura de sinterización, mientras que la incorporación de Nd3+ incrementa la temperatura de Curie y tan ó, siendo interesante el estudio del efecto combinado de la doble sustitución. En este trabajo se prepararon mezclas estequiométricas de polvos de Y2O3, Nd2O3, Bi2O3 y Fe2O3 para obtener NdxBi0.8Y2.2-xFe5O12 (O <= x <= 1.5, Dx=0.3); se evaluó el efecto del dopaje sobre las propiedades magnéticas y dieléctricas. La síntesis se realizó mediante molienda de alta energía, los polvos resultantes fueron compactados uniaxialmente, aplicando 900 MPa y sinterizados hasta 900°C durante 6 horas. Mediante Difracción de rayos X (DRX) se confirmó la introducción de iones de Bi3+ y Nd3+ en la estructura cristalina para x <= 1.2, y para mayores niveles de sustitución, se formó YFeO3. Los resultados de magnetometría de muestra vibrante (MMV) muestran disminución en los valores de magnetización de saturación (Ms) y coercitividad (Hc); hasta ~23 emu/g y 33 Oe respectivamente. Adicionalmente, en el intervalo de frecuencias de 50 Hz hasta 5 MHz, los valores de permitividad relativa (Er) van cambiando de 33.5 a 1.4 con pérdidas dieléctricas (tan ó) en el rango O.9-0.003, presentando disminución conforme incrementa la frecuencia.

Published: May 2022

It is no secret that 3 Kg LPG gas is difficult to access for the underprivileged. These commodities often experience scarcity and price increases at the retail level. In addition, the middle-class group also consumes 3 kg of LPG gas. This study uses a qualitative approach with a descriptive analysis research type. The results showed that 3 Kg LPG gas should be distributed to underprivileged communities who have been recorded with proof of ID cards and family cards. However, there was fraud in the distribution process which caused a scarcity of 3 Kg LPG gas. LPG gas was even sold for more than the highest specified retail price. This commodity is sold freely at retail kiosks in Matangkuli District, North Aceh Regency. Gas prices follow a demand and supply mechanism. The local government is not serious about controlling violations of the gas distribution process for poor families. As a result, market forces beat the policies formulated by the government. ABSTRAKSudah bukan rahasia umum gas LPG 3 Kg sulit diakses oleh masyarakat kurang mampu. Komoditas ini acapkali mengalami kelangkaan dan kenaikan harga di tingkat pedagang eceran. Selain itu, gas LPG dinikmati pula oleh kelompok kelas menengah. Penelitian ini menggunakan pendekatan kualitatif dengan tipe penelitian deskriptif analisis. Hasil penelitian menunjukkan bahwa gas LPG 3 Kg seharusnya disalurkan kepada masyarakat kurang mampu yang sudah terdata dengan bukti KTP dan KK. Namun terjadi kecurangan baik oleh oknum pihak pangkalan maupun agen yang menyebabkan kelangkaan gas LPG 3 Kg. Gas LPG bahkan dijual melebihi HET (harga eceran tertinggi) yang ditentukan. Komoditas ini dijual bebas di kios-kios eceran di Kecamatan Matangkuli Kabupaten Aceh Utara dengan mengikuti mekanisme permintaan dan penawaran, sementara pemerintah daerah tidak cukup serius mengendalikan pelanggaran proses distribusi gas untuk keluarga miskin. Alhasil kecerdikan pasar selalu bisa melampaui kebijakan-kebijakan yang dirumuskan oleh pemerintah.

Dünyada birçok alanda büyük değişim ve dönüşüm yaşanmasına sebep olan Covid-19 küresel salgın sürecinin temelini, dijital bir hayat oluşturmaktadır. Bu süreçte; müzeler bilgi teknolojilerini kullanarak toplumsal işlevlerini sürdürmüşler, koleksiyon ve sergilerini etkin bir biçimde erişime sunarak, ziyaretçilerinin müze ile iletişim kurmasını sağlamışlardır.
Günümüzde müzeler ziyaretçilerine gerek “kurumsal web siteleri” gerek “sosyal medya platformları” gerekse “mobil uygulamalar” aracılığıyla da ulaşabilmekte, izleyicisinin beklentilerine dijital ortamda da cevap vermektedirler. Teknolojinin gelişmesi ile müzecilikte; yeni bir yol haritası çizilmesi gerektiği konusunda farkındalık oluşmuştur. Dijital teknolojiler, müzeler için zengin bir bilgi kaynağı oluşturmaya ve bu bilgileri paylaşmaya yardımcı olmaktadır. Müze ile ilgili bilgiler, müze kitapları, koleksiyon, sergiler gibi birçok bilgiye web siteleri üzerinden ulaşılmaktadır.
Bu araştırma, var olan durumu belirlemeye yönelik olduğundan “betimsel tarama” modelindedir. Bu araştırmada, müzelerin ziyaretçileriyle daha etkili ve aktif etkileşim kurabilmesi için dijital teknolojiler özelinde web sitesi kullanımının etkisi değerlendirilmektedir. Bu amaçla; yargısal örnekleme ile seçilen müzelerin web siteleri incelenerek, etkili bir iletişim stratejisi geliştirmek için öneriler sunulmuştur.
Bu araştırmanın bulgularına göre; ülkemizdeki vakıf müzelerinden “OMM- Odunpazarı Modern Müze” web sitesinin görsel tasarımı; temiz, yalın ve estetik, tipografik öğeleri okunabilir, işlevsellik açısından ise; kullanıcı odaklı, işlevsel, mobil uyumlu, dinamik bulunmuştur. Ulusal bir müze olan Anadolu Medeniyetleri Müzesi’nin “koleksiyona ait detaylı bilgilerinin, güncel sergi, etkinlik ve duyuruların” yer alacağı özel bir web sitesinin olması gerekmektedir. TRT Yayıncılık Tarihi Müzesi web sitesi ülkemizdeki diğer kurum müzelerinin web siteleri ile karşılaştırıldığında tasarım açısından başarılı bulunmuştur. Fakat duyuruların güncel olmadığı görülmektedir ve sosyal medya kullanımı açısından geliştirilmesi gerekmektedir. Görsel ve içerik tasarımı etkili olan bir web sitesi, kullanıcılarında müzeye gitme isteği uyandırmaktadır. Dünyaca ünlü müzeler arasında yer alan “Metropolitan Sanat Müzesi ve Louvre Müzesi” görsel ve içerik açıdan etkili web sitesine sahiptir ve koleksiyon ile ilgili detaylı bilgiler, güncel duyurular ve sergiler bu müzelerin web sitelerinde yer almaktadır.

Повсякдення інтернованих вояків Армії УНР у таборах Стшалково і Каліш, Польща, крізь призму публікацій журналу «Наша Зоря» (1921–1923 рр.)
Authors: Срібняк Ігор , Палієнко Марина 
Published: May 2022

У статті проаналізовано матеріли таборового часопису «Наша Зоря», які висвітлювали деякі аспекти побуту та життєдіяльності інтернованих вояків-українців Армії УНР у таборах Стшалково і Каліш протягом другої половини 1921 – і до квітня 1923 рр. Встановлено, що на його шпальтах закарбовувались непохитна віра українського вояцтва у перемогу та стійкість таборян у подоланні щоденних труднощів, а разом з тим – ностальгія за Батьківщиною та хвилеві сумніви, коли під непосильним тягарем побутових проблем здавалося би що всі надії на відновлення української державності були втрачені.
Протягом усього часу свого існування «Наша Зоря» відчувала моральну та фінансову підтримку з боку таборян, які уділяли часопису дещицю із своїх зароблених тяжким трудом коштів. Дуже вагомо допомагали журналу й таборові інституції – проводячи різні культурно-мистецькі акції (театральні вистави, вечорниці, концерти) та перераховуючи отримані за це кошти до видавничого фонду «Нашої Зорі».
Разом з тим, попри цю підтримку зібраних коштів ледь-ледь вистачало аби звести «кінці з кінцями» та опублікувати чергове число часопису, і саме цим обумовлювались окремі випадки недотримання редакцією черговості виходу «Нашої Зорі». Але саме завдяки ентузіазму та спільним зусиллям гурту однодумців, які об’єднались у складі нечисленної редколегії цього видання, всі перепони успішно додалися.
Проведений аналіз матеріалів з історії таборового повсякдення українського вояцтва дає всі підстави стверджувати, що вони довший час слугували об’єднавчим чинником для таборян, скріплюючи їх моральний дух. Водночас, вони справляли потужний вплив на формування національної свідомості інтернованих вояків Армії УНР, зміцнюючи їх віру у визволення України від більшовизму.

ЛІТЕРАТУРНО-КРИТИЧНА РЕЦЕПЦІЯ ПРОЗИ ВОЛОДИМИРА ЯВОРІВСЬКОГО
Authors: Белінська Юліана 
Published: May 2022

У статті проаналізовано літературно-критичну рецепцію творчої спадщини Володимира Яворівського – талановитого прозаїка, публіциста, громадського діяча, лауреата Національної премії України імені Тараса Шевченка. Систематизовано результати дослідження жанрово-стильової своєрідності новел, повістей, романів В. Яворівського в українському літературознавстві, що, безперечно, сприятиме цілісному уявленню про творчу індивідуальність письменника. Доробок Володимира Яворівського став об’єктом поодиноких літературознавчих розвідок та характеризується неоднозначністю поглядів. Подекуди думки літературознавців не лише різняться, а й виявляються діаметрально протилежними. Різні аспекти творчості письменника окреслені в сучасних наукових студіях Двуличанської О., Клочека Г., Мацевича А., Панченка В., Якубовської М. та інших. Зважаючи на недостатню кількість науково-критичних розвідок, присвячених багатогранному творчому спадку Володимира Яворівського, чимало його граней залишаються нерозкритими, особливо це стосується останніх романів письменника. Початковий етап творчості Володимира Яворівського характеризується превалюванням малих та середніх жанрових форм (новела, оповідання, повість у новелах). Такі жанрові особливості прози зумовлені внутрішніми факторами, які пов’язуємо з досить молодим віком письменника, недостатністю життєвого досвіду. Згодом помічаємо поступовий перехід від малих до середніх та великих жанрів. На ранньому етапі у творчості В. Яворівського переважають елементи імпресіоністичного та неоромантичного стилів, а от в подальших періодах художньої еволюції письменника спостерігаємо реалістичну спрямованість творів. Амбівалентність поглядів на творчість Володимира Яворівського зумовлена його світоглядною позицією, різноманітністю її стилістичних та жанрових якостей, яке дає плідне підґрунтя для подальших досліджень у цьому напрямку.

Exosomes are membrane-enclosed vesicles secreted by cells, containing a variety of biologically active ingredients including proteins, nucleic acids and lipids. In this study, we investigated the therapeutic effects of the exosomes and underlying mechanisms in a miniature pig model of ischemia/reperfusion-induced acute kidney injury (I/R-AKI). The exosomes were extracted from cultured human umbilical cord derived mesenchymal stem cells (hUC-MSCs) and infused into a miniature pig model of I/R AKI. Our results showed that 120 min of unilateral ischemia followed by reperfusion and contralateral nephrectomy resulted in renal dysfunction, severe kidney damage, apoptosis and necroptosis. Intravenous infusion of one dose of exosomes collected from about 4 × 108 hUC-MSCs significantly improved renal function and reduced apoptosis and necroptosis. Administration of hUC-MSC exosomes also reduced the expression of some pro-inflammatory cytokines/chemokines, decreased infiltration of macrophages to the injured kidneys and suppressed the phosphorylation of nuclear factor-κB and signal transducer and activator of transcription 3, two transcriptional factors related to inflammatory regulation. Moreover, hUC-MSC exosomes could promote proliferation of renal tubular cells, angiogenesis and upregulation of Klotho and Bone Morphogenetic Protein 7, two renoprotective molecules and vascular endothelial growth factor A and its receptor. Collectively, our results suggest that injection of hUC-MSC exosomes could ameliorate I/R-AKI and accelerate renal tubular cell repair and regeneration, and that hUC-MSC exosomes may be used as a potential biological therapy for Acute kidney injury patients.

Published: May 2022

Introduction: Metabolic syndrome (MetS) is increasingly common in adults as well as in children and adolescents. However, preventing and treating MetS is one of the most pressing challenges for public health services worldwide. At present, the only approved treatments for MetS are dietary changes and physical activity, which are associated with a high rate of non-compliance. On the contrary, no drugs are licensed to treat metabolic syndrome, although a number of drugs are used to treat individual metabolic abnormalities, which increases the risk of adverse events, particularly in children. Policaptil Gel Retard® (PGR), an oral macromolecule complex based on polysaccharides, has been demonstrated to significantly reduce body weight, peak blood glucose (BG) levels, insulin levels, and lipid levels, providing an interesting non-pharmacological therapeutic option for MetS-associated metabolic abnormalities, especially in younger patients.Aims: To review available studies on the use of PGR in children, adolescents, or adults with obesity or metabolic syndrome.Methods: A systematic search of electronic databases for PGR and MetS. A total of six studies were identified and included.Results: Across four randomized clinical studies and one retrospective clinical study including a total of 359 obese children and adolescents with or without MetS and 157 overweight/obese adults with or without MetS and/or T2DM, a single dose of PGR resulted in a reduction in appetite and postprandial triglyceride levels in younger patients and peak postprandial BG levels in adults. Decreased lipid levels were observed in adults following a normocaloric diet who received PGR for 30 days. As a long-term treatment, in combination with a low-glycemic index diet with or without metformin, PGR resulted in reduced body mass index and waist circumference, improved insulin sensitivity with reduction of glucose-metabolism abnormalities, increased insulin reserve and, finally, an improved circulating lipid profile, regardless of age. No safety issues were reported.Conclusion: Policaptil Gel Retard® is an effective and safe non-pharmacological approach to improve the treatment of MetS-associated cardiovascular risk factors in children, adolescents, and adults.
Effects of Fracture Formation Stage on Shale Gas Preservation Conditions and Enrichment in Complex Structural Areas in the Southern Sichuan Basin, China

Published: May 2022

Fractures have significantly impacted the preservation, enrichment, and productivity of shale gas in the Longmaxi Formation in the complex structural area of the southern Sichuan Basin. Based on outcrop, core, imaging logging, inclusion analysis, acoustic emission experiments, and burial and thermal evolution history data, the formation stage, evolution and preservation conditions of structural fractures were comprehensively studied. Shear fractures are the main features of tectonic origin and are characterized by small widths, wide spacing, and high filling degrees. The structural fractures of the Longmaxi Formation can be divided into three groups in terms of their formation stage. The first-stage fractures were formed in the middle-late period of the Yanshanian tectonic movement (86.2–68.5 Ma), when the palaeotectonic stress was 68.33–71.82 MPa; and the homogenization temperature of the fluid inclusions in the corresponding fracture fillings is 150–178°C. The second-stage fractures were formed at the end of the Yanshanian -early Himalayan tectonic movement (68.5–35.2 Ma), when the palaeotectonic stress was 85.2–100.5 MPa; the homogenization temperature of the corresponding fluid inclusions is 123–148°C. The third-stage tectonic fractures formed during the middle-late period of the Himalayan tectonic movement (35.2–0 Ma), when the palaeotectonic stress was 55.6–63.8 MPa; fillings are scarce in these fractures, but the measured homogenization temperature of the corresponding fluid inclusions is 90–110°C. Shale gas preservation conditions were affected by the fracture formation stage, maximum horizontal crustal stress, fault scale, structural burial depth, formation pressure coefficient, etc. Three types of favourable preservation conditions were identified. The Type I target area is the low slope area in the middle of the syncline, which occurs more than 2.0 km from the fault. The research results have guiding significance for the evaluation of the preservation conditions of deep shale gas in the study area and similar areas.

Published: May 2022

Sodium-ion batteries promise efficient, affordable and sustainable electrical energy storage that avoids critical raw materials such as lithium, cobalt and copper. In this work, a manganese-based, cobalt-free, layered NaxMn3/4Ni1/4O2 cathode active material for sodium-ion batteries is developed. A synthesis phase diagram was developed by varying the sodium content x and the calcination temperature. The calcination process towards a phase pure P2-Na2/3Mn3/4Ni1/4O2 material was investigated in detail using in-situ XRD and TGA-DSC-MS. The resulting material was characterized with ICP-OES, XRD and SEM. A stacking fault model to account for anisotropic broadening of (10l) reflexes in XRD is presented and discussed with respect to the synthesis process. In electrochemical half-cells, P2-Na2/3Mn3/4Ni1/4O2 delivers an attractive initial specific discharge capacity beyond 200 mAh g−1, when cycled between 4.3 and 1.5 V. The structural transformation during cycling was studied using operando XRD to gain deeper insights into the reaction mechanism. The influence of storage under humid conditions on the crystal structure, particle surface and electrochemistry was investigated using model experiments. Due to the broad scope of this work, raw material questions, fundamental investigations and industrially relevant production processes are addressed.

Published: May 2022

IntroductionAntenatal care (ANC) is one of the pillars of maternal and child health programs aimed at preventing and reducing maternal and child morbidity and mortality. This study aims to identify the factors associated with ANC use, considering both health care demand and supply factors in the single analysis.MethodsWe used data from the endline survey conducted to evaluate the impact of the performance-based financing (PBF) program in Burkina Faso in 2017. This study was a blocked-by-region cluster random trial using a pre–post comparison design. The sample was derived in a three-stage cluster sampling procedure. Data collection for the endline surveys included a household survey and a facility-based survey. Women of childbearing age who gave birth at least once in the past 2 years prior to this survey and residing in the study area for more than 6 months were included in this study. Multilevel statistical techniques were used to examine individual and contextual effects related to health care demand and supply simultaneously and thus measure the relative contribution of the different levels to explaining factors associated with ANC use.ResultsThe working women were five times [odd ratio (OR): 5.41, 95% confidence intervals (CI) 4.36–6.70] more likely to report using ANC services than the women who were not working (OR: 5.41, 95% CI 4.36–6.70). Women living in a community with high poverty concentration were 32.0% (OR: 0.68, 95% CI 0.50–0.91) less likely to use ANC services than those in a community with low poverty concentration. Women living in a community with a medium concentration of women's modern contraceptive use were almost two times (OR: 1.88, 95% CI 1.70–2.12) more likely to use ANC services than those living in a community with a low concentration of women's modern contraceptive use. Women living in the health area where the level of ANC quality was high were three times (OR: 2.96, 95% CI 1.46–6.12) more likely to use ANC services than those in the health area where the ANC quality was low.ConclusionPolicies that increase the opportunity for improving the average ANC quality at the health facility (HF), the level of women's modern contraceptive use and women employment would likely be effective in increasing the frequency of use of antenatal services.
