Wachlarz w Kościele Wschodnim i Zachodnim oraz w kulturze świata
Authors: Wasilewska Jolanta
Published: April 2020

Historia wachlarza, wydawałoby się przedmiotu zbytkownego (a nawet zbędnego), jest niezwykle bogata i ciekawa z punktu widzenia obyczajów, historii i historii sztuki. To zdumiewające, jak ta niewielka rzecz codziennego użytku, współcześnie zaliczana do utensyliów mody kobiecej, przez tysiąclecia pełniła wielorakie i ważne funkcje.

Od najdawniejszych czasów wachlarze były używane do ochłody, odpędzania owadów, ochrony przed słońcem czy do rozniecania ognia. W starożytnym Egipcie wachlarze paradne używane były przez faraonów i kapłanów jako atrybuty władzy i dostojeństwa. Do lat 50. XX wieku w Kościele Zachodnim były używane dwa wachlarze (flabella) jako wyróżnienie honorowe w procesjach, podczas których niesiono papieża na sedia gestatoria. W liturgii Kościoła Wschodniego do naszych czasów przetrwało używanie wachlarzy (ripidia), chociaż ich znaczenie stało się już zupełnie symboliczne.

Znane są także wachlarze bojowe. Wywodzą się z Dalekiego Wschodu, gdzie służyły przede wszystkim jako oznaka rangi oficerskiej, ale także jako broń. Używane były od VI do XVI wieku, kiedy to osiągnęły szczyt popularności.

Wachlarze do Europy przybyły wraz z wyprawami na Daleki Wschód. W XVII i XVIII wieku nastały złote czasy wachlarzy. Królowały w salonach wyższych sfer i na dworach królewskich całej Europy. Były symbolem dostatku, wykwintności i kokieterii bez względu na porę roku. Wachlarz stał się atrybutem damy. Największą popularność zyskały wachlarze składane.

Wachlarze wykonywane były z drewna, metali szlachetnych, kości słoniowej, szylkretu, skóry, pergaminu, jedwabiu, płótna, papieru, piór, także z liści; były rzeźbione, malowane, haftowane i ozdabiane klejnotami. Przybierały różne formy w zależności od zastosowania i potrzeb, były małe i duże, proste, składane, plisowane, okrągłe, półkoliste, w kształcie liścia, chorągiewki, na długim lub krótkim uchwycie.

Bidang gelincir diperkirakan berada pada kedalaman 14 m dari atas lereng dan 2,5 m – 7,5 m di bawah permukaan jalan dengan jenis lapisan batu napal, tanah aluvium, dan tanah lempung dan digolongkan menjadi bidang gelincir yang dalam dengan jenis kelongsoran luncuran.
Potential and orientation for specific tourism products for Dak Nong’s tourism development
Authors: Thanh Loan Ngo , Huu Nghia Le
Published: April 2020

The Politburo Resolution No.08 on developing tourism into a spearhead economic sector has brought about the advantages of promoting tourism activities by the exploitation of natural resources, reducing poverty, and boosting the citizen’s income. Under these beneficial conditions, Dak Nong province can have more opportunities to develop its local’ s economy by investing in tourism. However, the interrelation of both competition and cooperation with the Central Highlands provinces, Dak Nong, needs to determine its own way to enhance the competitiveness for tourism development.

Based on the theory of tourist destination attractiveness, the authors confirm that designing specific tourism products to promote destination image and to build up the attractiveness of tourist destinations in Dak Nong are necessary. Through assessment of the current situation and potential of tourism development, by using secondary information analyses and in-depth interviews, the result shows that tourism in Dak Nong has not been effectively exploited. In the coming time, specific tourism products based on resources from Dak Nong Geopark can be the key factors to promote the tourism image of Dak Nong.

Authors: Mercé Klein Jordi , Torrens Ainhoa , Juan Marta , Miranda-Guardiola Faustino
Published: April 2020

Los fármacos antiarrítmicos de clase IC son ampliamente utilizados para el tratamiento y prevención de arritmias supraventriculares. Aunque son fármacos seguros en pacientes sin enfermedad cardíaca estructural, la proarritmia es un efecto secundario potencialmente grave. Describimos el caso de una paciente que presentó un flutter auricular 1:1 inducido por flecainida, y que además se condujo con aberrancia y morfología de bloqueo de rama izquierda. En estos casos, se plantea el diagnóstico diferencial con taquicardias de origen ventricular, siendo esencial preguntar sobre el uso concomitante de fármacos antiarrítmicos.

Plasmablastic lymphoma mutational profile is undescribed. Here we performed a targeted exonic NGS analysis of 30 plasmablastic lymphoma cases with a B cell lymphoma dedicated panel and FISH for the detection of MYC rearrangements. A complete phenotyping of the neoplastic and microenvironment cell populations was also performed. We have identified an enrichment in recurrent genetic events in MYC (69% with MYC translocation or amplification and 3 cases with missense point mutations), PRDM1/Blimp1 and STAT3 mutations. These gene mutations were more frequent in EBV positive disease. Other genetic events included mutations in BRAF, EP300, BCR (CD79A and CD79B), NOTCH pathway (NOTCH2, NOTCH1 and SGK1) and MYD88pL265P. Immunohistochemical analysis showed consistent MYC expression, higher in cases with MYC rearrangements together with phospho-STAT3 (Tyr705) overexpression in cases with STAT3 SH2 domain mutations. Microenvironment populations were heterogeneous and unrelated with EBV, with an enrichment of Tumor Associated Macrophages (TAM) and PD1 positive T cells. PD-L1 was expressed in all cases in the TAM population but only in 5 cases in the neoplastic cells (4 out of 14 EBV positive cases). HLA expression was absent in the majority of PBL cases. In summary, Plasmablastic lymphoma mutational profile is heterogeneous and related with EBV infection. Genetic events in MYC, STAT3 and PRDM1/Blimp1 are more frequent in EBV positive disease. An enrichment in TAM and PD1 reactive T lymphocytes is found in the microenvironment of PBL cases, that express PD-L1 in the neoplastic cells in a fraction of cases.
Chemical and biological potentialities of the ethyl acetate extracts of Drynaria quercifolia tuber and leaf

Published: April 2020

The ethyl acetate extracts of Drynaria quercifolia tubers and leaves were studied for their chemical and biological potentialities. The tuber extract was enriched with more reducing power compared to the leaf extract. But, the phenolic content was higher in the leaf extract compared to the tuber extracts. However, both the extracts were comparably cytotoxic and showed broadspectrum antimicrobial activity. The antimicrobial compound in the tuber extract was nonpolar. The findings suggested that the ethyl acetate extracts of D. quercifolia may have active principles for the development of promising phytotherapeutics.

Identification and comparison of three carp fishes based on mitochondrial 16S rRNA gene
Authors: Jahan Hawa , Akter Maria , Begum Rowshan Ara , Md Shahjahan Reza
Published: April 2020

Identification of Labeo rohita, L. bata and L. gonius is sometimes problematic when usual morphological features are lost and it is difficult to differentiate them with traditional morphological features at their diverse developmental stages. PCR-sequencing provides an authentic alternative means of identification of individuals at species level. Three local carp fishes were collected and 16S rRNA genes were sequenced by sanger sequencing method after PCR amplification using universal primers. Obtained sequences were found accurate with blast search result which showed maximum range of similarity with the existing respective gene fragments present in GenBank database. Sequences were compared and multiple sequence alignment has revealed some polymorphic sites which can be used to differentiate these three species from one another. This study may provide valuable understanding to study their population in future.

Authors: Manjur Monija , Hossain Sonia , Khan Md Harunor Rashid
Published: April 2020

A pot experiment with two acid sulfate soils of Badarkhali and Cheringa series were performed. After 18 years of fallow period in 2016, a crop trial was done in order to evaluate the response of rice plant without giving additional treatments. The average maximum temperature during the experimental period was 33.2ºC and average rainfall was 57 mm. Two cultivars of rice BRRI 48 and BRRI hybrid dhan 06 showed the tallest plant height of 115 cm and tillers 6.31 in numbers/plant on an average in both the soils. Panicle length was 16.5 cm, 1000-grain weight 22 g, grain yield 4.72 g/m2 and harvest index was 0.01 on average in both the soils. The experiment indicates that soil condition for crop growth possesses good quality after a long time and growth and yield parameters found satisfactory and significant (p ≤ 0.05).

Phytoavailability of chromium in chromium salt and poultry feed
Authors: Khan Tazeen Fatima , Roy Samapti , Rashid Md Harunur
Published: April 2020

A pot-culture experiment was conducted to investigate phytoavailability of chromium in inorganic chromium salt and raw poultry feed made from tannery waste. Poultry feed from tannery waste was applied to the soil at a rate of 5 t/ha while inorganic chromium salt was applied at a rate of 10 mg/ kg and 810 mg/kg. An upland leafy-vegetable commonly known as Kalmi (Ipomoea aquatica) was used to assess the phytoavailability. Physico-chemical analyses of all soil and plant samples were done at 0, 15, 30 and 45 days of incubation to assess chromium phytoavailability and also its effects on the uptake of other heavy metals viz., lead and iron. Plants treated with Cr showed declined vegetative growth, low accumulation of dry matter, reduced nutrient concentration and reduced nutrient uptake. It was found that the plants accumulated higher amount of Cr from raw poultry feed treated soil compared to that of the inorganic Cr salt treated soil. The effect of treatments on Cr accumulation both in root and shoot was found significant. The study concludes that Cr is phytoavailable depending on the source and increased concentration of Cr decreases accumulation of Pb and Fe and thereby likely to decrease uptake of these metals.

Published: April 2020

Bagarius bagarius (Hamilton, 1822), a freshwater catfish species, is important as food and game fish in Bangladesh, Bhutan, India and Nepal. In Bangladesh, it is known as Baghair and has been enlisted as critically endangered (CR) species in the IUCN Red List of Bangladesh 2000 and 2015, under the criteria A2cd version 3.1 mentioning declining trend in its population around 80% during the last 25 years (3 generation time). We studied the abundance of B. bagarius at 8 sites in three riverine habitats. We identified 8 individuals of B. bagarius from the Meghna river only (Shibpur site, Bhola Sadar). However, focus group discussion with fishers revealed that the species was frequently present in the catch from the river, although the abundance reduced considerably over the decade. We also found several other studies which reported the abundance of B. bagarius in different natural habitats. The findings from this study in combination with other published literature in the last 5 years indicated that the current status of B. bagarius in natural waters in Bangladesh do not fall below the threshold limits of CR species. Therefore, B. bagarius should be reclassified into a lower threatened status (but not Least Concern) than the current CR.

Effects of vermicompost and compost on soil properties and growth and yield of Kalmi (Ipomoea aquatica Forsk.) in mixed soil
Authors: Nasrin Afroja , Khanom Sayma , Hossain Shahid Akhtar
Published: April 2020

An incubation study was conducted to find out the best mixing ratio of acid and calcareous soil (maintaining 70% moisture) for pot experiment. Depending on various physico-chemical properties mixed soil 1 : 1 (i.e. acid : calcareous) was selected for pot experiment. The pot experiment was carried out to observe the effects of vermicompost and compost on soil properties and growth and yield of Kalmi (Ipomoea aquatica Forsk.). This experiment included seven treatments with three replications including control. Treatment variables were T0 (control), T1 (4 t/ha vermicompost), T2 (8 t/ha vermicompost), T3 (12 t/ha vermicompost), T4 (4 t/ha compost), T5 (8 t/ha compost) and T6 (12 t/ha compost). All the treatments had significant positive effects over control on growth and yield of kalmi. The highest growth and yield were recorded with T3 (12 t/ha vermicompost) treatment. In case of, macro and micronutrient uptake treatment T3 (12 t/ha vermicompost) performed best followed by T6 (12 t/ha compost) over T0 (control). However, in post-harvest soil except soil reaction (pH); electrical conductivity (EC), organic carbon (OC), available N, P, K, S, Ca, Mg, Na, Fe and Zn significantly increased for T3 (12 t ha-1 vermicompost) than T1, T2, T4, T5, T6 and T0.

Determining initial psychometric properties of parenting sense of competence scale in the context of Bangladesh
Authors: Ferdowshi Nafiza , Sultana Niger
Published: April 2020

The purposes of the present study were to translate the Parenting Sense of Competence (PSOC) scale and to determine its initial psychometric properties. Three hundred mothers were selected as participants from Dhaka city who have children aged 6 to 10 years. Collected data were analyzed to determine psychometrics by using Cronbach alpha, Spearman-Brown’s split-half and exploratory factor analysis. Results showed that internal consistencies were: Cronbach α = 0.663 and split-half reliability r = 0.636. As both internal consistencies value were quite similar that would make PSOC scale’s reliability more supportive. Initially validity was conducted on pilot basis by measuring content validity and construct validity (r = 0.628, p < 0.01). Study limitations and further implications were also discussed.

Published: April 2020

Wildlife diversity (amphibians, reptiles, birds and mammals) of Kashimpur Union in Gazipur Sadar Upazila under Gazipur district was studied from May, 2015 to March, 2016. A total of 110 species of wildlife belonging to 58 families under 19 orders were recorded. Among them, 6 (5.45%) species were amphibians, 14 (12.72%) reptiles, 72 (65.45%) birds and 18 (16.38%) were mammals. Among the amphibians, 5 (83.33%) species were frogs and only one (16.67%) was toad; of reptiles, 7 (50%) species were lizards, 5 (35.71%) snakes and 2 (14.29%) were tortoises. Of the birds, 39 (54.16%) species were passerines and remaining 33 (45.84%) were non-passerines. Resident status shows that 66 (91.62%) species were resident, 5 (7.00%) migrants and 1 (1.38%) species were vagrant. Among the mammals, 8 (44.45%) species were rodents, 4 (22.22%) flying mammals and 6 (33.33%) species were carnivorous mammals. The relative abundance shows that 10 (9.09%) species were very common, 24 (21.81%) common, 31 (28.19%) fairly common and 45 (40.91%) species were few. Considering the conservation status, 5 species were near threatened and 105 were the least concern nationally. According to Shannon-Wiener (H = 3.287) and Simpson's (D = 0.942) diversity indices, diversity of birds was higher than the other wildlife observed. Some potential threats on wildlife diversity were identified such as habitat degradation and fragmentation, expansion of agricultural lands and urbanization. Therefore, conservation and management are necessary in order to protect the diversity of existing wildlife and their population in the study area.

Low growth resilience of subarctic rhodoliths (Lithothamnion glaciale) to coastal eutrophication
Authors: Bélanger D , Gagnon P
Published: April 2020

Eutrophication is one of the most important drivers of change in coastal marine ecosystems worldwide. Given their slow growth, rhodoliths and the biodiverse communities they support are regarded as non-renewable resources threatened by human activity. Consequences of nutrient enrichment on growth and calcification in crustose coralline algae are equivocal, and even more so in cold-water rhodoliths. We paired a 183 d laboratory mesocosm experiment with a 193 d field experiment on Newfoundland (Canada) rhodoliths (Lithothamnion glaciale) to test the hypothesis that nutrient (nitrate, ammonia, and phosphate) enrichment and biofouling reduce rhodolith growth. Rhodoliths in the laboratory were exposed to 1 of 3 nutrient concentrations (ambient, intermediate, or high) and either of 2 levels of manual cleaning (cleaned or uncleaned) to control biofouling. We exposed rhodoliths in the field to 1 of 2 nutrient concentrations (ambient or elevated). Eutrophication in the laboratory did not affect biofouling; however, manual cleaning reduced biofouling by ~4 times relative to uncleaned rhodoliths. Rhodoliths grew 2 times slower at elevated than ambient nutrient concentrations, and ~27% more in cleaned than uncleaned rhodoliths at all concentrations. Rhodoliths in the field also grew significantly slower under elevated than ambient phosphate concentrations, but only during the first 6 wk, indicating some capacity for long-term recovery. We conclude that despite some growth resilience to low and infrequent increases in nutrient concentrations, subarctic L. glaciale rhodoliths cannot cope with prolonged exposure to modest eutrophication.

Can the Presence of Ovarian Corpus Luteum Modify the Hormonal Composition of Follicular Fluid in Mares?
Authors: Satué Katiuska , Fazio Esterina , Medica Pietro
Published: April 2020

The hypothesis of this study was to investigate if the presence of corpus luteum (CL) in one ovary could modify the hormonal content of follicular fluid (FF) in the follicles. Sixty ovaries were taken after the slaughter of 30 clinically healthy mares. In relation to the sizes, the follicles were classified into three different categories, as small (20–30 mm), medium (31–40 mm) and large (≥41 mm). Blood samples were collected from the jugular vein of mares before their slaughter, and then the FF samplings were extracted from each single follicle. The ovaries that were collected were classified into two groups, according to the presence (CL-bearing) or absence (non-CL-bearing) of CL. The serum and FF samples were analysed for progesterone (P4), oestradiol-17β (E2), testosterone (T), androstenedione (A4) and dehydroepiandrosterone (DHEA). Intrafollicular P4 concentrations in large follicles of CL-bearing groups were lower than for non-CL-bearing ones. Intrafollicular E2 concentrations increased with the increase of the follicle diameter in both groups, CL-bearing and non-CL-bearing. However, in the FF with a large and medium follicle size, E2 concentrations were significantly higher in non-CL-bearing groups than in CL-bearing groups. T and A4 significantly increased in the large and medium follicle sizes when compared to the small follicle sizes in both groups, but higher concentrations in the non-CL-bearing group were obtained.

Efficient Regional Hybrid Ensemble-Variational Data Assimilation using the Global-Ensemble-Model-Augmented Error Covariance for Numerical Weather Prediction over Eastern China
Authors: Wang Yuanbing , Chen Yaodeng , Min Jinzhong
Published: April 2020

An efficient regional hybrid ensemble-variational (EnVar) data assimilation method using the global-ensemble-model-augmented error covariance is proposed and preliminarily tested in this study. This method uses the global ensemble error covariance as the complementary low-resolution regional ensemble error covariance. The high-resolution dynamic ensemble mean is used as the first guess in hybrid EnVar and then re-centered to the updated high-resolution dynamic ensemble perturbations after minimization analysis. In this study, the proposed method is implemented into the Weather Research and Forecasting Model’s (WRF) data assimilation system coupled with the ensemble transform Kalman filter (ETKF) and preliminarily tested for numerical weather prediction during the Mei-Yu season over eastern China. It is found that the experiment containing fewer regional dynamic ensemble members but augmented with global ensemble error covariance obtains similar results to the experiment containing many more regional dynamic ensemble members. However, the former experiment only takes up one third of the latter experiment’s computational cost. The method proposed in this study also outperforms the 3DVar, hybrid EnVar using the pure global ensemble error covariance, as well as the hybrid EnVar using regional ETKF ensemble with a smaller size. The method proposed in this paper effectively combines the contributions of the ensemble error covariance from both the global and the regional models to produce better initial conditions for the regional WRF data assimilation system.
Speed of Processing and Personality: The Influence of Personality and Extrinsic Feedback on the Performance of Cognitive Tasks
Authors: Wong Ming Yu Claudia , Chung Pak Kwong , Leung Ka Man
Published: April 2020

Background: Feedback is considered as an effective means of motivating, guiding, and reinforcing desired behaviours. However, the ways to interpret external feedback may be different among individuals with different personality traits; therefore, this would influence the effects of feedback on performance. Accordingly, the influencing effects of personality towards different styles of feedback on cognitive task performance were examined. Methods: Participants (N = 71) were given three Stroop tasks as a dependent variable, whereas the Trail Making Task was an independent variable; additionally, a personality test was used to record the personality traits of each participant. The relationship between personality and feedback-induced changes in Stroop performance was computed by means of Pearson correlation, followed by a mixed-effect model to demonstrate the effect of personality on the overall performance with feedback. Results: The statistical analysis indicated that performance from those with higher levels of extraversion generally profitted from feedback, irrespective of whether it was negative feedback (r = 0.201) or positive feedback (r = 0.205). Additionally, the moderating effect of personality on feedback and performance was demonstrated. Conclusions: The limitations of the sample size and other external influences may have reduced the representativeness of the research. Nonetheless, more potential influencing factors need to be included and explored in future research.

Published: April 2020

Herein, we demonstrate a method used to tune the selectivity of LaNiO3 (LNO) perovskite catalysts through the substitution of La with K cations. LNO perovskites were synthesised using a simple sol-gel method, which exhibited 100% selectivity towards the methanation of CO2 at all temperatures investigated. La cations were partially replaced by K cations to varying degrees via control of precursor metal concentration during synthesis. It was demonstrated that the reaction selectivity between CO2 methanation and the reverse water gas shift (rWGS) could be tuned depending on the initial amount of K substituted. Tuning the selectivity (i.e., ratio of CH4 and CO products) between these reactions has been shown to be beneficial for downstream hydrocarbon reforming, while valorizing waste CO2. Spectroscopic and temperature-controlled desorption characterizations show that K incorporation on the catalyst surface decrease the stability of C-based intermediates, promoting the desorption of CO formed via the rWGS prior to methanation.

Published: April 2020

Photocatalysts with a superior activity range, from ultraviolet (UV) to near-infrared (NIR) light, are attractive for solar utilization. From this perspective, sulfides are promising due to their narrower bandgap than oxides. In this report, NaBiS2 was synthesized hydrothermally under mild conditions by adjusting the alkaline amount. The rough NaBiS2 nanosheets possessed various surface atomic configurations on their surfaces, including amorphous clusters and amorphous nano-domains, revealed by HRTEM. A theoretical investigation of the band structure employing the density functional theory (DFT) method for the first time indicated that NaBiS2 is an indirect bandgap semiconductor with a narrow bandgap of 1.02 eV. Experimentally, it showed excellent photocatalytic activity for the degradation of methyl blue under UV, visible light and NIR light due to its experimental bandgap width of 1.32 eV. A degradation rate of 99.6% was reached after 80 min under full spectrum irradiation.

Published: April 2020

Collateral artery growth (arteriogenesis) involves the proliferation of vascular endothelial cells (ECs) and smooth muscle cells (SMCs). Whereas the proliferation of ECs is directly related to shear stress, the driving force for arteriogenesis, little is known about the mechanisms of SMC proliferation. Here we investigated the functional relevance of the potassium channels KV1.3 and KCa3.1 for SMC proliferation in arteriogenesis. Employing a murine hindlimb model of arteriogenesis, we found that blocking KV1.3 with PAP-1 or KCa3.1. with TRAM-34, both interfered with reperfusion recovery after femoral artery ligation as shown by Laser-Doppler Imaging. However, only treatment with PAP-1 resulted in a reduced SMC proliferation. qRT-PCR results revealed an impaired downregulation of α smooth muscle-actin (αSM-actin) and a repressed expression of fibroblast growth factor receptor 1 (Fgfr1) and platelet derived growth factor receptor b (Pdgfrb) in growing collaterals in vivo and in primary murine arterial SMCs in vitro under KV1.3. blockade, but not when KCa3.1 was blocked. Moreover, treatment with PAP-1 impaired the mRNA expression of the cell cycle regulator early growth response-1 (Egr1) in vivo and in vitro. Together, these data indicate that KV1.3 but not KCa3.1 contributes to SMC proliferation in arteriogenesis.

Rice (Oryza sativa L.) seedlings grown under nitrogen (N) deficiency conditions show a foraging response characterized by increased root length. However, the mechanism underlying this developmental plasticity is still poorly understood. In this study, the mechanism by which N deficiency influences rice seminal root growth was investigated. The results demonstrated that compared with the control (1 mM N) treatment, N deficiency treatments strongly promoted seminal root growth. However, the N deficiency-induced growth was negated by the application of zeatin, which is a type of cytokinin (CK). Moreover, the promotion of rice seminal root growth was correlated with a decrease in CK content, which was due to the N deficiency-mediated inhibition of CK biosynthesis through the down-regulation of CK biosynthesis genes and an enhancement of CK degradation through the up-regulation of CK degradation genes. In addition, the N deficiency-induced decrease in CK content not only enhanced the root meristem cell proliferation rate by increasing the meristem cell number via the down-regulation of OsIAA3 and up-regulation of root-expressed OsPLTs, but also promoted root cell elongation by up-regulating cell elongation-related genes, including root-specific OsXTHs and OsEXPs. Taken together, our data suggest that an N deficiency-induced decrease in CK content promotes the seminal root growth of rice seedlings by promoting root meristem cell proliferation and cell elongation.

Published: April 2020

The immune response is critical in the maintenance of an organism’s health. The immune response can be broken down into two groups. The innate response, which is fast-acting and rids the body of most foreign material before infection occurs, and the adaptive response, a more specific defense against pathogen composed mostly of antibody production and killer cells. Linking the two responses via cytokine and chemokine secretion are macrophages, motile phagocytic cells that ingest and present foreign material playing a role in the innate and adaptive immune response. Although macrophages are necessary for the survival of an organism, studies have also shown macrophages play a more sinister role in the initiation, progression, and metastasis in tumorous cells. In this comprehensive review, we show how macrophages induce such a response through abnormal cellular signaling and creating a cellular microenvironment conducive for tumor growth and metastasis, as well as the future outlook of this field.

Published: April 2020

Interactions between components of model lipid membranes (spherical lipid bilayers and liposomes) are investigated here. Parameters characterizing equilibria in the 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC)-diosgenin (Dio) and 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC)-diosgenin acetate (DAc) membrane systems have been determined. The interfacial tension measurement of spherical lipid bilayers was based on the Young-Laplace’s equation using a homemade computer-controlled device. We assume a 1:1 complex in the DPPC-Dio and DPPC-DAc membrane systems. The parameters A 3 − 1 , the surface concentration of lipid membranes formed from these complexes, γ 3 , the interfacial tension of such membranes, and, K, the constant stability of these complexes were calculated. Microelectrophoresis was used for examinations of the surface charge density of lipid membranes. The values were obtained here from electrophoretic mobility data applying Smoluchowsky’s equation. The effect of pH (pH ranged of 2 to 10) on the electrolyte solution and the compositions of the membranes was analyzed. The obtained results indicate that the modification of DPPC membranes with both Dio and DAc causes changes in surface charge density values and shifts of the isoelectric point.

Published: April 2020

Based on entropy characteristics, some complex nonlinear dynamics of the dynamic pressure at the outlet of a centrifugal compressor are analyzed, as the centrifugal compressor operates in a stable and unstable state. First, the 800-kW centrifugal compressor is tested to gather the time sequence of dynamic pressure at the outlet by controlling the opening of the anti-surge valve at the outlet, and both the stable and unstable states are tested. Then, multi-scale fuzzy entropy and an improved method are introduced to analyze the gathered time sequence of dynamic pressure. Furthermore, the decomposed signals of dynamic pressure are obtained using ensemble empirical mode decomposition (EEMD), and are decomposed into six intrinsic mode functions and one residual signal, and the intrinsic mode functions with large correlation coefficients in the frequency domain are used to calculate the improved multi-scale fuzzy entropy (IMFE). Finally, the statistical reliability of the method is studied by modifying the original data. After analysis of the relationships between the dynamic pressure and entropy characteristics, some important intrinsic dynamics are captured. The entropy becomes the largest in the stable state, but decreases rapidly with the deepening of the unstable state, and it becomes the smallest in the surge. Compared with multi-scale fuzzy entropy, the curve of the improved method is smoother and could show the change of entropy exactly under different scale factors. For the decomposed signals, the unstable state is captured clearly for higher order intrinsic mode functions and residual signals, while the unstable state is not apparent for lower order intrinsic mode functions. In conclusion, it can be observed that the proposed method can be used to accurately identify the unstable states of a centrifugal compressor in real-time fault diagnosis.

Published: April 2020

Blockchain technology is increasingly used worldwide to enhance the performance and profit of any environment through its defining characteristics, such as security, auditability, immutability, and inconspicuousness. Owing to these characteristics, the blockchain can be used in various non-financial operations of some domains, such as the Internet of Things (IoT) and distributed computing. However, implementing blockchain technology in IoT is not always a feasible solution because blockchain deployment is costly, it has limited extensibility and provides irregular bandwidth and latency. In this regard, a simple size extensible (SSE) blockchain has been proposed to provide an optimal solution for IoT environments by satisfying the needs of the IoT environment as well as ensuring end-to-end security. The implementation of the proposed blockchain develops an overlay network to obtain a distributed environment where the blockchain is handled by the resources present therein. Two novel algorithms were introduced into the proposed system to minimize the irregularity and latency on one hand, and to maximize the throughput of the system on the other. The shared-time depending agreement algorithm (STD) minimizes the irregularity in the extraction operation and latency. The other, the shared throughput administration algorithm (STA) justifies the overall collection of the transmission load in the network and maintains the performance of the blockchain. The proposed system was applied to smart home IoT appliances to test the performance of the proposed system. The experimental results show that the proposed blockchain system minimizes nearly 70% of the data irregularity, latency, and furthermore, 30% of the blockchain extensibility is maximized as compared to the existing systems.

Published: April 2020

The results of a techno-economic model of distributed wind-hydrogen systems (WHS) located at each existing wind farm on the island of Ireland are presented in this paper. Hydrogen is produced by water electrolysis from wind energy and backed up by grid electricity, compressed before temporarily stored, then transported to the nearest injection location on the natural gas network. The model employs a novel correlation-based approach to select an optimum electrolyser capacity that generates a minimum levelised cost of hydrogen production (LCOH) for each WHS. Three scenarios of electrolyser operation are studied: (1) curtailed wind, (2) available wind, and (3) full capacity operations. Additionally, two sets of input parameters are used: (1) current and (2) future techno-economic parameters. Additionally, two electricity prices are considered: (1) low and (2) high prices. A closest facility algorithm in a geographic information system (GIS) package identifies the shortest routes from each WHS to its nearest injection point. By using current parameters, results show that small wind farms are not suitable to run electrolysers under available wind operation. They must be run at full capacity to achieve sufficiently low LCOH. At full capacity, the future average LCOH is 6–8 €/kg with total hydrogen production capacity of 49 kilotonnes per year, or equivalent to nearly 3% of Irish natural gas consumption. This potential will increase significantly due to the projected expansion of installed wind capacity in Ireland from 5 GW in 2020 to 10 GW in 2030.

Published: April 2020

This study analyzes the hydrodynamic performance and application of a pitching float-type wave energy conversion device under complex sea conditions in the South China Sea. Potential flow theory and ANSYS-AQWA software are used to establish a method for analyzing hydrodynamic performance in both time and frequency domains, as well as the various factors that influence hydrodynamic performance. The frequency domain characteristics of the conversion device are explored, as well as the time-domain characteristics when exposed to regular and irregular waves. The results show that the frequency domain of hydrodynamic performance conforms to the requirements of an offshore mobile platform. A mooring point that is closer to the center of mass leads to improved stability of the conversion device. The angle arrangement of the anchor-chain mooring method fully conforms to safety requirements. When the wave direction is 45°, the conversion device is highly stressed and its movement is the most strenuous; however, the device can operate safely and stably under all working conditions. These results provide a significant reference for expanding the wave-energy capture range and the hydrodynamic performance of floating wave-energy conversion devices.
