Symbolism in Poe's "The Haunted Palace"
Authors: Kuhon Fiola
Published: March 2019

ABSTRACTPoetry always has a unique charm that captivates and draws the reader into its figurative world. One of the most interesting charm is symbolism used by the poet, in one single word lays a deeper explanation beyond what is perceptible by the eyes. Therefore, the aim of this research was to reveal the symbolism in “The Haunted Palace”, a gothic-themed poetry written by a well-known poet Sir Edgar Allan Poe. Having analyzed this poetry, the writer later found that Poe’s “The Haunted Palace” has some unique symbols used by the poet himself. Despite of writing long and descriptive lines, the poet chose appropriate symbols that lead the readers to think and conjecturing more deeply. Every symbol used in “The Haunted Palace” represents simplicity, authenticity and brilliancy of Poe himself. Thus, a symbolism holds a very important role of poetry. It is not only pleasantly presented but also elucidating things beyond its literal substance. It proves that Poe’s “The Haunted Palace” is pleasant to be read but difficult to be interpreted.Keywords: poetry, symbolism, The Haunted Palace, Edgar Allan Poe
Property relations between spouses in private international law

Published: March 2019

This article deals with the issues of regulation of property relations of spouses in private international law. The article deals with the conflict issues of marriage, as well as the contractual regime of property of spouses. The article reveals the content of the Minsk and Chisinau conventions on property relations between spouses. In particular, the conventions say that the property relations between spouses are determined by the legislation of the Contracting party in whose territory they live together. If the husband lives in one Contracting state and the wife in the other and both have the same nationality, the law of the country of which they are nationals governs their property relations. Attention is paid to bilateral agreements on legal assistance to States in the field of property relations between spouses. For example, such an agreement exists between Russia and Estonia, and it helps to resolve various property issues between spouses. The domestic legislation of different States regulates the issue of determining the regime of matrimonial property in different ways. For example, in the States of the Anglo-Saxon legal system and in most Muslim countries there is only a regime of separate property. On the contrary, in the States of the Romano–German legal system, preference is given to the regime of common property of spouses, and it is possible to establish a different regime of property relations by agreement of the spouses. According to this principle and developing family law in Russia.

MEMBINCANG KEMBALI HUBUNGAN SYARIAH DAN FILSAFAT
Authors: Rosyid Maskur
Published: March 2019

Mempertentangan Filsafat dengan Agama (Syariah) sama dengan mempertentangkan akal dengan wahyu sebagai sumber kebenaran. Diskursus tersebut memuncak ketika al-Ghazālī memberikan kritik tajam atas filsafat. Kritik tersebut dikritik oleh Ibn Rushd. Lebih dari itu, upaya rekonsiliasi filsafat dan Syariah diberikan oleh Ibn Rushd. Epistemologinya dibangun atas tiga hal, metode al-Khaṭabiyah (Retorika), metode al-Jadaliyyah (dialektika), dan metode al-Burhāniyyah (demonstratif) yang dilakukan dengan metode takwil. Dalam Bahasa uṣūl al-fiqh, Ibn Rushd menggunakan metode al-jam’ wa al-tawfīq. Akal dan wahyu diposisikannya secara proporsional. Akal dan wahyu sama-sama digunakan sebagai alat untuk menemukan pengetahuan tanpa mengunggulkan yang satu di atas yang lainnya.

Background: Dental schools are highly demanding and students are exposed to different stress factors which affect their academic performance. Identification of the potential sources of stress is important in the dental education programme, as it gives opportunity to take various measures to prevent stress in the dental school environment. The aim of this study was to examine the perceived stressors in dental undergraduate students studying at a private institution in a metro city. Materials and Methods: A questionnaire based cross-sectional study was conducted among 176 third and fourth year students, interns and externs of a dental school who gave written voluntary consent. The instrument used to record stress was a pre-validated questionnaire, i.e., the modified version of the Graduate Dental Environmental Stress scale. Results were recorded on a four point Likert scale. The mean GDES30 score was calculated across the sample and also compared across categories such as gender, year of study and residence using the one way ANOVA test. The questionnaire was divided into various domains such as academic, clinical, patient, faculty, financial, insecurity regarding professional future and personal domains and the stress levels compared across the same. Results: The mean GDES30 score across the sample was 2.44(SD=0.43) corresponding to somewhat stressful on the Likert scale. Significantly higher mean GDES30 scores were seen in the domains of insecurity regarding professional future followed by clinical and patient domains. Significantly higher stress levels were seen in females compared to males and interns compared to all other years of study. Conclusion: Moderate stress levels were perceived in the clinical year dental students participating in this study. Regulatory bodies and counsellors should focus on helping students cope with stress, thereby improving the performance of students as well as their quality of life and overall health.

Published: March 2019

Research into the symbiotic relationship between plants and arbuscular mycorrhizal fungi (AMF) is key for sustainable agricultural intensification. The objective of the present study is to evaluate native AMF at the monosporic level in greenhouse-grown, economically important crops. Agricultural soil samples from three locations (Saltillo, Zaragoza, and Parras) were obtained by combining portions resulting from a zigzag sampling pattern. From these samples, 15 morphotypes were extracted according to a modified Gerdemann’s technique and monosporically inoculated on melon, cucumber, tomato, and onion, 30 days after their sowing. Under a completely random experimental design, 16 treatments with three repetitions were defined. Plant height, root length, stem diameter, total fresh weight, fresh root weight, dry root weight, bulb weight, fresh leaf weight, total dry weight, flower number, leaf number, fruit number, spore number, and percentage of colonization were all evaluated. The results were subjected to the analysis of variance (ANOVA) and the Tukey comparison test (p ≤ 0.05), which showed that the monosporic inoculation favors significantly the AMF and the host, while the T6 (Saltillo spore + Steiner modified with 20% of the normal phosphorus concentration) showed a greater response uniformity on onion and melon, which indicates its great potential as an inoculum.

Published: March 2019

This 2-year field experiment investigated the effects of full straw incorporation on soil fertility and crop yield in a rice-wheat (Oryza sativa L.–Triticum aestivum L.) rotation on sandy, loamy soil. Two treatments were tested: (i) straw removal (CK) and (ii) straw incorporation (STR). The STR significantly increased the wheat yield by an average of 58% compared with CK; however, no significant difference was found in the rice yield. Soil available nitrogen, phosphorus, and potassium in the 0–20 cm soil layer increased by more than 15% with STR compared to CK. The soil cation exchange capacity and organic carbon in the 0–20 cm soil layer increased by 8% and 22%, for STR compared to CK, respectively. Straw incorporation significantly elevated the soil saturated water content but decreased the soil bulk density compared with CK. Soil aggregates >2 mm were significantly increased after straw return. STR also notably increased the soil urease, invertase, and catalase activities in the 0–15 cm soil layer by 11.4%, 41.0%, and 12.9%, respectively, and the soil microbial carbon and nitrogen contents in the 0–20 cm soil layer by 59% and 54%. Therefore, full straw incorporation could significantly improve soil fertility and maintain crop yields for the study area.

Published: March 2019

Bioaerosols from swine confinement buildings (SCBs) pose a challenge to public health,and microorganisms within the SCBs bioaerosols originate from swine feces, of which the microbialcomposition is associated with the production phase. The present study adopted the wholemetagenome shotgun sequencing approach, to assess the effects of the production phase on thecomposition and functional potential of microbial populations in SCBs bioaerosols. Most annotatedproteins were assigned into domain bacteria, within which the predominant phylum was Firmicutes.The taxonomical profiles of bioaerosols from different types of piggeries showed that buildingshousing weaning piglets (WP) exhibited higher abundances of Bacteroidetes and Proteobacteria thanbuildings housing finishing pigs (FP), gestating sows (GS), farrowing sows (FS), and breeding boars(BB). Regarding the functional potential, the WP bioaerosol had more genes involved in the proteinturnover and fewer genes involved in the carbohydrate metabolism than bioaerosols from othertypes of SCBs. Furthermore, production phase influenced the antibiotic resistance genes (ARGs)profile of the SCBs bioaerosols. Bioaerosol microbiome of BB, shared a high similarity with GS, andWP bioaerosol microbiome was more similar to FP than other types of SCBs. Our study suggeststhat the production phase plays a key role in the SCBs bioaerosol microbiome.

The study investigates the effect of carbon nanotubes on chloride penetration in nano-modified mortars and reports on the physical, electrical, and mechanical performance of the material. Mortars were artificially corroded and their surface electrical surface conductivity as well as flexural and compressive strength were measured. The influence of variable nanotube concentration in accelerated corrosion damage was evaluated. Nanotube concentration was found to significantly affect the permeability of the mortars; improvements in flexural and compressive response of mortars exposed to salt spray fog, compared to virgin specimens, were rationalized upon decreases in the apparent porosity of the materials due to filling of the pores with sodium chloride. Electrical resistivity was found to increase up to two orders of magnitude with respect to the surface value; above the percolation threshold, the property impressively increased up to five orders of magnitude.

Authors: Den Hartogh Danja J. , Tsiani Evangelia
Published: March 2019

Type 2 diabetes mellitus (T2DM) is a metabolic disease characterized by insulin resistance and hyperglycemia and is associated with personal health and global economic burdens. Current strategies/approaches of insulin resistance and T2DM prevention and treatment are lacking in efficacy resulting in the need for new preventative and targeted therapies. In recent years, epidemiological studies have suggested that diets rich in vegetables and fruits are associated with health benefits including protection against insulin resistance and T2DM. Naringenin, a citrus flavanone, has been reported to have antioxidant, anti-inflammatory, hepatoprotective, nephroprotective, immunomodulatory and antidiabetic properties. The current review summarizes the existing in vitro and in vivo animal studies examining the anti-diabetic effects of naringenin.

Published: March 2019

Muscle regeneration, characterized by the activation and proliferation of satellite cells and other precursors, is accompanied by an inflammatory response and the remodeling of the extracellular matrix (ECM), necessary to remove cellular debris and to mechanically support newly generated myofibers and activated satellite cells. Muscle repair can be considered concluded when the tissue architecture, vascularization, and innervation have been restored. Alterations in these connected mechanisms can impair muscle regeneration, leading to the replacement of functional muscle tissue with a fibrotic scar. In the present review, we will discuss the cellular mediators of fibrosis and how the altered expression and secretion of soluble mediators, such as IL-6 and IGF-1, can modulate regulatory networks involved in the altered regeneration and fibrosis during aging and diseases.

Water is a key resource for sustainable development and plays a crucial role in human development. Desalination is one of the most promising technologies to mitigate the emerging water crisis. Thermal desalination and reverse osmosis are two of the most widely employed desalination technologies in the world. However, these technologies are energy intensive. Clathrate-hydrate-based desalination (HyDesal) is a potential energy-efficient desalination technology to strengthen the energy–water nexus. In our previous study, we proposed a ColdEn-HyDesal process utilizing waste Liquefied Natural Gas (LNG) cold energy based on a fixed-bed reactor configuration. In this study, we evaluated the effect of 10% propane in three different gas mixtures, namely, nitrogen (G1), argon (G2), and carbon dioxide (G3), as hydrate formers for the HyDesal process. The achieved water recovery was very low (~2%) in the presence of NaCl in the solution for gas mixtures G1 and G2. However, high water recovery and faster kinetics were achieved with the G3 mixture. To improve the water recovery and kinetics of hydrate formation for the G2 gas mixture, the effect of sodium dodecyl sulfate (SDS) was evaluated. The addition of SDS did improve the kinetics and water recovery significantly.

The adsorption and migration of sulphur (S) atoms on the diamond (001) surface were investigated through first principles calculations to discover the inherent law in S-doped diamond film growth. Results indicated that deposited S atoms could abstract the hydrogen atom on the surface. The adsorption energies were in a range of 2.47 to 5.5 eV when S atoms were deposited on the hydrogen terminated surface or the surface with open radical sites (ORSs). The S atom could migrate on the surface of the 3ORS slabs and the energy barrier was approximately 1.35 eV. The calculations of the projected density of states and the analysis of the magnetic moments presented an interesting result, which demonstrated the evolving phenomena in S-doped diamond film growth and discovered the inherent laws. On the 2ORS slabs, the magnetic moment of the S atom became 0.000 μB after bonding with the two carbon atoms. In such case, a new doped C atom combined with the S atom with a triple bond, and then the C–S molecule was desorbed from the surface. The abstraction of the adsorbed S atom results from the fact that S atoms have six electrons in their outermost electron shell. This finding revealed the reason behind the low S incorporation and the growth rate decrease in S-doped diamond film deposition. This discovery also indicated that atoms with six electrons in their outermost electron shell might hardly be doped into the diamond films during the deposition process.
Self-Ordered Orientation of Crystalline Hexagonal Boron Nitride Nanodomains Embedded in Boron Carbonitride Films for Band Gap Engineering

Boron carbonitride (BCN) films containing hybridized bonds involving elements B, C, and N over wide compositional ranges enable an abundant variety of new materials, electronic structures, properties, and applications, owing to their semiconducting properties with variable band gaps. However, it still remains challenging to achieve band gap-engineered BCN ternary with a controllable composition and well-established ordered structure. Herein, we report on the synthesis and characterization of hybridized BCN materials, consisting of self-ordered hexagonal BN (h-BN) crystalline nanodomains, with its aligned basal planes preferentially perpendicular to the substrate, depending on the growth conditions. The observation of the two sets of different band absorptions suggests that the h-BN nanodomains are distinguished enough to resume their individual band gap identity from the BCN films, which decreases as the carbon content increases in the BCN matrix, due to the doping and/or boundary effect. Our results reveal that the structural features and band gap of this form of hybrid BCN films are strongly correlated with the kinetic growth factors, making it a great system for further fundamental physical research and for potential in the development of band gap-engineered applications in optoelectronics.

We consider the problem of channel coding over multiterminal state-dependent channels in which neither transmitters nor receivers but only a helper node has a non-causal knowledge of the state. Such channel models arise in many emerging communication schemes. We start by investigating the parallel state-dependent channel with the same but differently scaled state corrupting the receivers. A cognitive helper knows the state in a non-causal manner and wishes to mitigate the interference that impacts the transmission between two transmit–receive pairs. Outer and inner bounds are derived. In our analysis, the channel parameters are partitioned into various cases, and segments on the capacity region boundary are characterized for each case. Furthermore, we show that for a particular set of channel parameters, the capacity region is entirely characterized. In the second part of this work, we address a similar scenario, but now each channel is corrupted by an independent state. We derive an inner bound using a coding scheme that integrates single-bin Gel’fand–Pinsker coding and Marton’s coding for the broadcast channel. We also derive an outer bound and further partition the channel parameters into several cases for which parts of the capacity region boundary are characterized.

One of the main objectives in education is to increase the motivation of the students to achieve meaningful learning. The use of technologies in classrooms which students are familiarized with such as the smartphone or the tablet, is a way to achieve this goal. On the other hand, it has been proven that the inclusion of scenarios supported by games and competition enhance the active participation of students. Therefore, in this work we present the results of a study based on of the application Kahoot with students of secondary education, in the subjects of mathematics, biology & geology and physics & chemistry, during the academic year 2017/2018. This tool allows students to answer to on-line questionnaires created by the teacher, through mobile devices, and check their results in a few seconds as well as those of their classmates. The results obtained on the assessment of the tool by students, in terms of the benefits in the learning process, have been very positive and help us to examine the potential of the use of on-line questionnaires in the classrooms.

Polyphenols and triterpenoids in olive have relevant importance both in the physiology of the plant and the nutritional and biological value of its products. Olive leaf extracts are of special interest for their numerous health-promoting properties. The present research is investigating the occurrence of phytochemicals in supercritical fluid extracts from leaves with regard to collection time and drying temperature. The phytochemical profiles of the olive leaf extracts were determined by reversed-phase high-performance liquid chromatography (HPLC) coupled to electrospray ionization time-of-flight mass spectrometry (ESI-TOF-MS) detection. The main extracted phytochemicals were phenols and terpenoids. A significant variation in the amounts of the different components was observed as a function of the different drying temperature and collecting time (p < 0.05). Among samples, the maximal contents of polyphenols and secoiridoid derivatives were found in the extracts from olive leaves collected in November and dried at 120 °C, whereas triterpenoids showed the highest content in fresh leaves collected in August.
