Cilj rada je empirijski ispitati postojanje povezanosti prometa u trgovini na malo i Pokazatelja pouzdanja potrošača na razini Europske unije i na razini euro područja. Pokazatelj pouzdanja potrošača (engl. Consumer Confi dence Indicator, CCI) je kompozitni pokazatelj ocjena i očekivanja potrošača u zemljama EU i EA. U istraživanju se ispituje mogućnost predviđanja smjera promjene prometa u trgovini na malo, a ne i intenziteta te promjene. Pri tome se ispituje povezanost predviđenih (po promjenama CCI-a) i ostvarenih promjena prometa u trgovini na malo (na godišnjoj razini) za određeno vrijeme prethođenja. U tu svrhu u analizi je korišten VAR model, Grangerov test uzročnosti, konfuzijska matrica i Hi-kvadrat test nezavisnosti obilježja u tablici kontingence. Uočeno je da promjene CCI-a prethode promjenama prometa u trgovini na malo dva (za EU) i tri (za EA) mjeseca i da su planirane i ostvarene promjene statistički značajno povezane. U oko 80% slučajeva su promjene za navedeno vrijeme prethođenja (na godišnjoj razini) istosmjerne. Dodatno su izračunani koeficijenti korelacije pomičnog okvira i utvrđena nestabilnost povezanosti među varijablama kroz vrijeme.

Full textAbstract:
Introduction: The pathophysiological development of long COVID (LC) is still insufficiently known. However, post infection fatigue syndromes were seen before, among other pathogens including Epstein-Barr virus (EBV). Considering EBV reservoir in COVID-19 patients, this review aims to present current knowledge related to EBV role in development of LC and with the potential diagnostic utility. EBV infection: Following the primary lytic infection of epithelial oropharyngeal and nasopharyngeal cells EBV establishes a very complex mechanism of lifelong survival in B cells. Latent infection with occasional viral reactivations constantly challenges the host's immune response. In individuals with immune imbalance including COVID-19, it could drive long-term consequences. EBV and COVID-19: The activity of EBV has been shown as the most prevalent human herpesvirus infection in COVID-19 population (41%). Correlation between lymphocytopenia-induced disability to remove the EBV, increases in EBV DNA viremia and COVID-19 complications have also been reported. EBV and long COVID: The positivity of EBV DNA during acute SARS-CoV-2 infection predicted the presence of symptoms up to 60 days after COVID-19. Association between EBV infection and symptoms such as brain fog, fatigue, arthralgia and skin rashes have been also described in post infection sequelae ME/CFS. Anti-EBV early antigen-diffuse (EA-D) IgG antibodies were detectable among two-thirds of respondents experiencing LC. Increases in anti-EBNA1 IgG levels analyzed months following COVID-19 onset in convalescent LC population could serve as a potential marker of EBV reactivation at the time of acute SARS-CoV-2 infection. Some authors also managed to show anti-EBV viral capsid antigen (VCA) IgM seropositivity in half of COVID-19 patients indicating of either coinfection or EBV reactivation. Conclusion: As a multisystemic illness, LC is without a defined spectrum of diagnostic and treatment options. Whereas EBV reactivation alone or together with other risk factors drives LC symptoms, further prospective studies involving different cohorts and tissue reservoirs are necessary to understand underlying biological mechanisms.

Sau 12 tháng triển khai nghiên cứu, đề tài đã hệ thống hóa cơ sở lý luận và thực tiễn xây dựng mô hình OCOP dựa vào nội lực cộng đồng và thực trạng triển khai chương trình OCOP tại tỉnh Đắk Lắk. Đến tháng 02/2022, toàn tỉnh có 72 sản phẩm được công nhận OCOP; trong đó có 64 sản phẩm đạt 3 sao, 08 sản phẩm đạt 4 sao. Để phát huy sức mạnh nội lực cộng đồng, chính quyền địa phương cần coi OCOP là chương trình phát triển kinh tế quan trọng, chủ lực của cộng đồng trong xây dựng nông thôn mới bền vững. Cần phải tập trung phát triển các sản phẩm có tiềm năng gắn với đơn vị làng xã để phát huy nội lực tại địa phương và phát triển các chuỗi giá trị sản phẩm. Thông qua chương trình tập huấn, hội thảo và các đợt điều tra khảo sát, hai sản phẩm tiềm năng của hai địa phương đã được lựa chọn để triển khai xây dựng mô hình OCOP dựa vào nội lực cộng đồng là sản phẩm Mắc ca của Hợp tác xã (HTX) Đàn Hương - Mac ca Vip Phú Lộc của xã Phú Lộc, Huyện Krông Năng và sản phẩm dệt thổ cẩm của HTX Dệt thổ cẩm Tơng Bông của xã Ea Kao, TP. Buôn Ma Thuột. Bên cạnh những tiềm năng, thuận lợi của các HTX như có nguồn lao động dồi dào, kinh nghiệm sản xuất và những hỗ trợ từ chương trình OCOP quốc gia đang triển khai..., các đơn vị cũng gặp không ít khó khăn như thiếu vốn sản xuất, kiến thức về thị trường và kỹ năng hoàn thiện hồ sơ đăng ký sản phẩm OCOP .... Vì vậy, cần có sự quan tâm hơn nữa của Nhà nước và chính quyền địa phương để hỗ trợ chủ thể hoàn thiện các thủ tục để đạt chứng nhận OCOP.

Full textAbstract:
Amaç: Bisfenoller (BP'ler), genel popülasyonun yaygın olarak kullandığı birçok üründe bulunan potansiyel hormon bozuculardır. Bisfenol A (BPA) ise, vücudun metabolik sistemleri üzerindeki olumsuz etkilerine rağmen, bazı plastik ve reçinelerin üretiminde uzun yıllardır kullanılan endüstriyel bir kimyasaldır. BPA gibi toksik ajanlardan ve dolayısıyla çevresel kirleticilerden etkilenen en önemli organlardan biri böbreklerdir. Ellajik asit (EA) fitokimyasal bir polifenol bileşiğidir ve yapılan birçok çalışmada EA’nın antioksidan, anti-mutajenik, anti-kanser ve anti-apoptotik özellikler sergilediği rapor edilmektedir. Bu çalışmanın amacı BPA ile indüklenen böbrek hasarı üzerine EA’nın etkisini ortaya koymaktır. Gereç ve Yöntemler: Bu çalışmada 24 adet erkek rat, Kontrol, BPA (30 gün süreyle 25mg/kg), EA (30 gün süreyle 10 mg/kg) ve BPA+EA (30 gün süreyle sırasıyla 25mg-10mg/kg) olarak dört gruba ayrıldı (n=6). Çalışma sonunda dekapite edilen ratlardan alınan böbreklerin ağırlıkları ile kan serumundan kan üre nitrojeni (BUN) ve kreatinin değerleri ölçüldü. Bunun yanında böbreklerin genel histolojik görüntüsünü ortaya koymak amacıyla Pikro Sirius Red boyaması, dokularda meydana gelen DNA hasarının ortaya konulabilmesi amacıyla 8-hidroksideoksiguanozin antikoru kullanılarak immunohistokimyasal boyama yapılmıştır. Bulgular: Yapılan değerlendirme sonucunda sol böbreğe ait mutlak ve nispi ağırlığın BPA grubunda artış gösterdiği, BPA+EA grubunda ise kontrole yaklaşarak düştüğü gözlenmiştir. Kan üre azotu (BUN) ve kreatinin değerlerinde BPA grubunda kontrol grubuna göre ciddi artış olduğu görülmüş, BPA+EA grubunda ise bu değerlerin azaldığı tespit edilmiştir. BPA kullanılan gruptan alınan böbrek dokularında 8-hidroksideoksiguanozin primer antikorunun glomerulus ve tubul yapılarında yoğun pozitif reaksiyon verdiği, glomerulus yapısında dejenerasyon ve vakuolizasyon olduğu, bazı bölgesel nekroz alanları bulunduğu ve tubul yapılarının bozulduğu gözlenmiştir. Buna karşın EA ve kontrol gruplarında birbirine benzer şekilde oldukça az 8-hidroksideoksiguanozin pozitif alana rastlanmıştır. BPA ve EA’nın birlikte kullanıldığı grupta ise gerek glomerulus yapısı gerek tubul yapılarında BPA’nın tek başına kullanıldığı gruba göre düzelmeler görülürken 8- hidroksideoksiguanozin pozitif alanların azaldığı gözlenmiştir. Sonuç: Toplumun her kesiminden bireylerin maruz kalma ihtimali olan BPA’nın böbrek dokusuna vereceği muhtemel zararların, EA içeren gıda katkı maddeleri kullanılarak azaltılabileceği sonucuna varılmıştır.

Full textAbstract:
The size effects in metal forming have been found to be crucial in micro-scale plastic deformation or micro-forming processes, which lead to attenuation of the material’s formability due to the increasing heterogeneity of the plastic flow. The use of an electric field during micro-scale plastic deformation has shown to relieve size effects, enhance the material’s formability, modify the microstructure, etc. Consequently, these electric-assisted (EA) micro-forming processes seem to bring many potential benefits that need to be investigated. Accordingly, here we investigated the influence of an electric field on the size effects to describe the fracture behavior in uniaxial micro-tension tests of an AZ31 alloy with various grain sizes. In order to decouple the thermal-mechanical and microstructure changes, room temperature (RT), oven-heated (OH), air-cooled (AC), and EA uniaxial micro-tension tests were conducted. The size effects contribution on the fracture stress and strain showed a similar trend in all the testing configurations. However, the smallest fracture stresses and the largest fracture strains were denoted in the EA configuration. EBSD examination shows that current-induced dynamic recrystallization (DRX) and texture evolution could be negligible under the studied conditions. The kernel average misorientation (KAM) maps give the larger plastic deformation in the EA specimens due to the reduction of plastic micro-heterogeneity. Finally, the fracture morphology indicates that the current-induced ductility enhancement may be attributed to the arrest of micro-crack propagation and the inhibition of void initiation, growth, and coalescence caused by lattice melting and expansion.

Full textAbstract:
Ellagic acid, a natural substance found in various fruits and nuts, was previously shown to exhibit beneficial effects towards metabolic syndrome. In this study, using a genetic rat model of metabolic syndrome, we aimed to further specify metabolic and transcriptomic responses to ellagic acid treatment. Adult male rats of the SHR-Zbtb16Lx/k.o. strain were fed a high-fat diet accompanied by daily intragastric gavage of ellagic acid (50 mg/kg body weight; high-fat diet–ellagic acid (HFD-EA) rats) or vehicle only (high-fat diet–control (HFD-CTL) rats). Morphometric and metabolic parameters, along with transcriptomic profile of liver and brown and epididymal adipose tissues, were assessed. HFD-EA rats showed higher relative weight of brown adipose tissue (BAT) and decreased weight of epididymal adipose tissue, although no change in total body weight was observed. Glucose area under the curve, serum insulin, and cholesterol levels, as well as the level of oxidative stress, were significantly lower in HFD-EA rats. The most differentially expressed transcripts reflecting the shift induced by ellagic acid were detected in BAT, showing downregulation of BAT activation markers Dio2 and Nr4a1 and upregulation of insulin-sensitizing gene Pla2g2a. Ellagic acid may provide a useful nutritional supplement to ameliorate features of metabolic syndrome, possibly by suppressing oxidative stress and its effects on brown adipose tissue.

Abstract INTRODUCTION AND OBJECTIVE: Enolase-1 (ENO1) and -2 (ENO2) are implicated in tumor metabolic and aggressive functions. Like prostate specific membrane antigen (PSMA), they localize to the tumor cell surface and are potential theranostics targets. ENO autoantibodies were reported by our group in prostate cancer (PCa) patients but their immunoreactivity to ENO1/2 isoforms was not defined. Differential ENO immunoreactivity in docetaxel-resistant (DR) PCa cells between African American (AA) and European American (EA) PCa patients was also reported. Our objective was to investigate the role of ENO isoforms in the race-related differential ENO immunoreactivity of PCa patients. METHODS: PCa patient sera (41 AA, 68 EA) were obtained from Loma Linda University Biospecimen Laboratory. Western blotting (WB) analysis, using patient sera and monoclonal antibodies to ENO1 and ENO2, was done against lysates from docetaxel-sensitive (DS) and DR PCa cell lines and against recombinant (rec) ENO1 and ENO2 to assess ENO isoform expression and detect ENO autoantibodies. Scratch-wound assay was performed to evaluate AA and EA anti-ENO driven inhibition of DR PCa cell migration. Student’s T-test and Chi-squared analyses were performed with p<0.05 deemed significant. RESULTS: ENO1 expression was robust in all assessed DS and DR cell lines. ENO2 was detected in DS cells but was significantly reduced in DR cells. PSMA expression was lost in cells expressing ENO1 and neuroendocrine markers. Anti-ENO EA sera reacted in WB with the expected 50 kD band in both DS and DR PCa cells, but anti-ENO AA sera reacted preferentially with this band in DS cells. Strong immunoreactivity was noted against recENO1 in AA and EA sera (7% vs 28%, p<0.01) and against recENO2 in AA and EA sera (24% vs 35%, p=0.23). EA, but not AA, ENO autoantibodies significantly inhibited DR cell migration, and their pre-absorption with recENO1 diminished this inhibitory effect. CONCLUSIONS: Autoantibodies to ENO1 and ENO2 were identified in EA and AA PCa patient sera. Weaker ENO1 immunoreactivity was seen in sera from AA PCa patients, corresponding with weaker inhibition of DR PCa cell migration compared to EA patient sera. Unlike PSMA and ENO2, ENO1 expression was robust in neuroendocrine-like DR PCa cell lines. Future studies will correlate the presence of ENO autoantibodies with clinicopathologic parameters in a larger patient cohort. Defining mechanisms underlying the race-related differential ENO immunoreactivity may identify novel biological determinants of PCa health disparities and uncover the theranostic potential of tumor surface ENO1.

A cinética da reação de decomposição térmica e termocatalítica do óleo de girassol foi avaliada com a utilização de métodos isoconversionais, i.e., FWO (Ozawa-Flynn-Wall) e KAS (Kissinger-Akahira-Sunose), em três taxas de aquecimento (5, 10 e 20 ºC min-1), na faixa de conversão entre 20% e 80%. Os métodos apresentam um nível de confiança, ao apresentarem numericamente valores de Ea, i.e., energia de ativação aparente, relativamente próximos. A decomposição térmica da oleaginosa ajudará a entender, nos limites estudados, os possíveis produtos para produção de combustível verde. No processo catalítico, os catalisadores microporoso H-ZSM-5 e mesoporoso Al-MCM-41 foram utilizados por apresentarem acidez elevada, o que ajudará na produção de um biocombustível com baixos teores de oxigenados. As energias de ativação aparente para 50% de conversão do óleo de girassol na ausência de catalisadores utilizando os métodos FWO e KAS foram 262,56 e 255,35 kJ mol-1, respectivamente; já, a mistura OGMH1 (na presença de material catalítico), apresentou para os mesmos 50% de conversão valores de Ea correspondentes a 152,23 e 143,18 kJ mol-1, respectivamente.

A review of novel kinetics models of dehydration (DH) of equilibrium swollen hydrogels: poly(acrylic acid) hydrogel (PAAH), poly(acrylic-co-methacrylic acid) (PAMAH), and poly(acrylic acid)-g-gelatin (PAAGH), is presented. Kinetic curves of isothermal and non-isothermal dehydration of hydrogels were measured using thermogravimetric methods. The kinetic complexity of the dehydration process was analyzed by different methods: integral, differential, Kissinger-Assakura-Sanura (KAS), and Vyzovkin’s method. The complex kinetics of dehydration of hydrogels was described by a series of new kinetic models: distribution apparent energy activation model (DAEM), Webull’s distribution of reaction times, the dependence of the degree of conversion (α) on the temperature which is defined by the logistic function, coupled single step-approximation and iso conversion curve. Procedures were developed for calculating the function of the density distribution of probability (g(Ea)) of apparent activation energy (Ea). The relationship between the phase state of the absorbed water in hydrogel and the form of function of distribution of apparent Ea and kinetic parameters of dehydration was analyzed.

Full textAbstract:
Abstract To boost the target production and to achieve the Kingdom of Saudi Arabia and the State of Kuwait visions, Khafji Joint Operations (KJO) started evaluating new projects to boost their daily production in 2020. KJO decided to drill an exploratory reentry well to confirm the existence of oil beyond the known area in one of its carbonate formations. This objective required drilling the longest reach reentry well in the field. The well challenges were to sidetrack from a vertical existing well with high-collision risk and passing through shaly formations associated with wellbore stresses and instability. Also, other difficulties were drilling across zones with high risks of lost circulation and geological uncertainty. To effectively ensure reducing the drilling cost and flawless operations, an integrated solution from different domains including drilling, geomechanics, petrophysics, mud logging, well placement and drilling fluids were included in the project. Drilling challenges have been reviewed from offset wells and previous drilling performance was analyzed to deliver a comprehensive well risk assessment. The risk assessment dictated different measures to be taken in the planning phase. First, a geomechanics study was used to optimize the trajectory design and define trajectory limits for each formation. Second, engineering analysis included a finite-element drilling dynamics study to evaluate combining the rotary steerable system (RSS) bottomhole assembly (BHA) with logging while drilling (LWD) to predict the dynamics and dogleg capability. Third, recommended drilling practices and roadmap were provided with contingency plans for anticipated risks. Finally, different drilling, formation evaluation, and geosteering services were included in the well design requirements to provide challenging well profile, real-time data assurance and decision making on reservoir fluid characterization, reservoir description, and detailed fracture characterization, which will be critical for proper well placement and delivering well objectives. The well was successfully drilled, meeting the required objectives and delivered the longest reentry lateral in Khafji offshore using the latest generation of RSS and full geosteering and petrophysical technologies which enabled a cost-effective well placement solution in a complex geological environment with high uncertainty. The well delivered the required reservoir evaluation objectives, which opens additional future opportunities with similar application in Khafji field.

Full textAbstract:
It was examined to evaluate the effectiveness of extracted tea leaves as the green corrosion inhibitor that contains mild steel in acidic solvents. The test specimens were dissolved in an acidic solution with different concentrations of the extracted tea leaves. After 3 hours of immersion, the corrosion rate (CR) was measured. The results showed that a concentration of 1000 mg/l caused a significant inhibition in corrosion rate as compared to control. To see how black tea (BT) extract affected mild steel corrosion in 1 M HCl, it was subjected to a loss of weight procedure. The corrosion level and the inhibitor's performance were examined at five different BT extract concentrations that included 0.4, 1 , 1.4 , 2, and 2.4 g/l. According to the findings, an increase in BT concentration at every temperature decreased CR. As a result of the rise in kinetic activities of the metal surface interface, typically, temperature elevation leads to an increase in CR at every concentration of BT extract. The study's findings showed that adding 2.4 g/l of inhibition efficiency resulted in a temperature of 323 K, resulting in 84.95% inhibition efficiency. The small activation energy (Ea) of 8.74 and 11.45 kJ/mole reflected the barrier layer properties of BT extract and its chemical interactions on mild steel surfaces. The thermodynamic parameter revealed the spontaneous interaction between BT extract species and steel surface as kad rose from 0.929 to 1.728 (g/l)-1.

Full textAbstract:
För att lindra flygsektorns klimatpåverkan har elektriskt flyg (Electric Aviation, EA) framstått som ett lovande alternativ. De nordiska länderna strävar efter att gå i bräschen för införandet av denna nya teknik och har satt upp ambitiösa mål för att implementera den inom en snar framtid. Men ett antal frågor måste besvaras och utmaningar lösas innan elektriskt flyg kan bli verklighet. Är det politiska engagemanget i Norden tillräckligt för att stötta dessa initiativ? Var ska den nödvändiga finansieringen komma ifrån? Är infrastrukturen och de tekniska framstegen som krävs på plats? Dessa huvudproblem och deras lösningar behandlas i detta policysammandrag.
