Authors: Brazhnуk  L. V.
Published: September 2020

Стаття присвячена теоретичним і практичним питанням формування, оцінки джерел інвестування та визначення векторів реалізації державної інвестиційної політики. У статті виокремлено та обґрунтовано основні ідеології представників різних течій механізму інвестування, а також представлено зарубіжні практики ведення інвестиційної діяльності. Розглянуто тенденції стану капітальних інвестицій, зокрема структура за джерелами фінансування, динаміка та структура за видами економічної діяльності, темпи приросту, здійснено оцінку їх співвідношення до ВВП та порівняння результатів з рекомендованими нормативами, що свідчать про його низький рівень економічного зростання в Україні.
Метою статті є дослідження еволюції інвестиційних моделей та процесів на вітчизняному інвестиційному ринку.
Наукова новизна. Обґрунтовано тенденції у сфері інвестування та визначено рівень забезпечення капіталовкладеннями для умов ефективної економіки та можливості функціонування розширеного відтворення, що дозволило запропонувати пріоритетні вектори реформування державної інвестиційної політики у контексті специфічних неспроможностей трансформаційної економіки.
Висновки. Аналіз показав, що основним джерелом фінансування інвестицій залишаються власні кошти підприємств, є потреба у нарощуванні обсягів фінансових інвестицій шляхом розвитку фінансового посередництва, та найбільш привабливою сферою інвестування є промисловість. Спостерігаються негативні явища інвестиційних процесів в аграрному секторі, невтішний прогноз у короткостроковій перспективі щодо активізації інвестиційної активності у сільському господарстві, оскільки потенційні інвестори зайняли позицію очікування прийняття закону обігу земель. За результатами проведеного дослідження обґрунтовано інвестиційні процеси в країні, розкрито проблеми сьогодення та приділено увагу питанням реалізації державної інвестиційної політики у контексті загальносвітових тенденцій.
The inclusive and sustainable industrial development policy: which way for Nigeria?
Authors: Paul  S. O. , Chikelue Ofuebe
Published: September 2020

The United Nations, as usual, demonstrated a commitment by the formulation of «Inclusive and Sustainable Industrial Development» (ISID) to alleviate poverty through job creation in response to the realisation of SDG–9. With a descriptive research design and the documentary analysis method, it is found through this research that in spite of the policy, Nigerian industrial development efforts are not impressive. It is realised that both developed nations and the Nigerian government lack sincerity in the implementation of the policy.
The purpose of the article is to canvass for a demonstration of a strong commitment by the UN and the Nigerian government, strengthening of science and technological institutions of learning for result-oriented Research & Development; and enactment of a law that will criminalise importation of goods that can be produced locally.
The scientific novelty. In this paper, the foundation for the study, the research problem, nature of Nigerian industrialisation, the commitment of Nigerian government and stimulation of the policy in the actualisation of industrialisation in Nigeria are discussed with the adoption and application of «Endogenous growth theory».
Conclusions. Conclusively, it is paramount to clearly state that the introduction of ISID is targeted at encouraging full participation, empowerment, and control over resources allocation in response to the SDGs which brought about the development of global policy and productivity enhancement for social advancement. Notwithstanding, therefore, it is found through this research that though there are various industrial development policies, and medium-term economic plans at both local and international levels, the portrait of Nigerian industrialisation is not impressive.
Thus, many countries in the world are diversifying their sources of income. Nigeria is therefore expected to re-invigorate its manufacturing sector like other developed economies of the world by engaging sustained improvements and proactive activities as the sine-qua-non for dismantling the vicious circle of poverty and the realisation of a self-reliant and dynamic economy. So, developed human resources through rigorous R&D are tantamount to industrial services that will be central to the efforts of Nigeria to develop her socio-economic status.

Asrayanti As. Management Analysis of Maccini Baji Fish Landing Bases in Pangkajene and Kepulauan Regency. Guided by Danial and Ihsan. Study aims to analyze the improvement of the functions and infrastructure facilities of PPIs and formulate management strategies. This research was conducted in May to July 2018. The survey method was supported by primary and secondary data with a Purposive Sampling system. Data analysis is utilization analysis and SWOT analysis. The results showed that the facilities contained in the PPI Maccini Baji for pond ponds need to be dredged as deep as 2.25 m because they have a shallow depth of 0 meters at the lowest tide. Meanwhile, the dock is still in the form of a revetment so that in the future it is necessary to build a pier. Ice Factory Facilities and SPDN also still require additional stock to meet all the requirements around the PPI. From the results of the SWOT analysis showing the coordinates of 1.4: 1.25 which are in the quadrant I position or aggressive strategy, this condition is to support an aggressive growth policy (growth oriented strategy) by maximizing every strength possessed and utilizing existing opportunities. Strategic steps that can be taken are; developing an effective marketing system and improving service and convenience for fishermen who utilize PPI, as well as integrated licensing.

Published: September 2020

MWCNT/starch composites were prepared by simple solution casting method by incorporating upto 1.0 wt. % of multi-walled carbon nanotubes (MWCNTs) as reinforcing fillers in the starch matrix. Gelatin was used as dispersing agent to disperse the MWCNTs into aqueous solution and glycerol was used as plasticizer to form composites. SEM images of the MWCNT/starch composite show the homogenous surface of the composite where CNTs are embedded into the starch matrices. XRD spectra of the composite show no characteristic peaks of CNTs in the starch matrix. FTIR spectra show peaks at around 3435 and 2927 cm-1 indicating that the covalent bonds between –OH groups and C-H groups of soluble starch and CNT were formed in the composite. Electrical conductivity of the composite was enhanced from 2.85×10-9to 5.28× 10-8 S/m due to the addition of CNTs at room temperature and decreased with the increase of temperature. UV visible spectra showed increasing absorption with increasing CNTs content in the composite. TGA analysis demonstrated the stability of the MWCNT/starch composite.

Precision medicine in nonalcoholic fatty liver disease: New therapeutic insights from genetics and systems biology
Authors: Sookoian Silvia , Pirola Carlos J.
Published: September 2020

Despite more than two decades of extensive research focusing on nonalcoholic fatty liver disease (NAFLD), no approved therapy for steatohepatitis—the severe histological form of the disease—presently exists. More importantly, new drugs and small molecules with diverse molecular targets on the pathways of hepatocyte injury, inflammation, and fibrosis cannot achieve the primary efficacy endpoints. Precision medicine can potentially overcome this issue, as it is founded on extensive knowledge of the druggable genome/proteome. Hence, this review summarizes significant trends and developments in precision medicine with a particular focus on new potential therapeutic discoveries modeled via systems biology approaches. In addition, we computed and simulated the potential utility of the NAFLD polygenic risk score, which could be conceptually very advantageous not only for early disease detection but also for implementing actionable measures. Incomplete knowledge of the druggable NAFLD genome severely impedes the drug discovery process and limits the likelihood of identifying robust and safe drug candidates. Thus, we close this article with some insights into emerging disciplines, such as chemical genetics, that may accelerate accurate identification of the druggable NAFLD genome/proteome.

Penelitian ini melihat bahwa solidaritas Etnis Tionghoa di Kota Kendari dilandasi beberapa unsur-unsur dan memiliki landasan pengintegrasian solidaritas. Tujuan penelitian ini yaitu untuk mendeskripsikan bentuk-bentuk solidaritas pada Etnis Tionghoa di Kota Kendari dan mendeskripsikan identitas etnis yang dijadikan sebagai simbol pengelompokan sosial. Jenis penelitian yang dilakukan pada penelitian ini yaitu menggunakan metode kualitatif. Teknik pengumpulan data dilakukan melalui penelitian lapangan (field research) yang meliputi wawancara, pengamatan dan dokumentasi. Bentuk-bentuk solidaritas yang terbangun pada Etnis Tionghoa di Kota Kendari tidak dilakukan secara perorangan, melainkan berkelompok dan kerjasama. Solidaritas yang terbangun pada Etnis Tionghoa hingga saat ini tidak terlepas dari peristiwa di masa lalu yang mengharuskan Etnis Tionghoa untuk solid dibawah tekanan pemerintah dan diskriminasi dari berbagai pihak masyarakat di masa lalu. Tekanan dan diskriminasi dari berbagai pihak membentuk mereka sebagai etnis yang eksklusif dan tidak melibatkan masyarakat yang tidak ada keterkaitanya dengan Etnis Tionghoa. Namun, solidaritas yang dilakukan Etnis Tionghoa saat ini telah mengalami perubahan. Kesan ekslusif tidak lagi tepat digunakan untuk kalangan Etnis Tionghoa karena mereka telah melakukan pembauran dengan berbagai aktivitas solidaritas untuk masyarakat umum. Hal tersebut sebagai wujud loyalitas Etnis Tionghoa di tempat mereka bermukim. Pada Etnis Tionghoa di Kota Kendari, hal tersebut dapat dilihat melalui Yayasan Budi Mulia Kendari sebagai peyedia fasilitas sosial untuk masyarakat umum, aktivitas solidaritas Paguyuban Sosial Marga Tionghoa Indonesia (PSMTI) Sulawesi Tenggara dan solidaritas antar Etnis Tionghoa di Kota Kendari.
Supplemental LED Increases Tomato Yield in Mediterranean Semi-Closed Greenhouse
Authors: Palmitessa Onofrio Davide , Paciello Paolo , Santamaria Pietro
Published: September 2020

Supplemental light (SL) is a technique used to increase horticulture yield, especially in northern countries, where the Daily Light Integral (DLI) is a limiting factor during fall and winter, and which could also be used to obtain higher tomato yield at the Mediterranean latitude. In this study, three tomato hybrid (F1) cultivars were grown for year-round production in a commercial semi-closed glasshouse in Southern Italy: two of the cherry fruit-type (‘Juanita’ and ‘Sorentyno’) and one mini plum fruit-type (‘Solarino’). From 120 to 243 days after transplant, light-emitting diode (LED) toplights were used as SL, with a photoperiod of 18 h. The main climatic parameters inside and outside the glasshouse were recorded, and tomato plants’ development and yield were examined. Plants grown with LEDs had longer stems as compared to control treatment (9.53 vs. 8.79 m), a higher stem thickness and yielded more trusses. On average, the yield was 21.7% higher with LEDs. ‘Sorentyno’ was the cultivar with the highest cumulated productivity when it was grown under SL. However, the cultivar with best light use efficiency under LEDs was ‘Solarino’. Therefore, supplemental LED from mid-December until March enhanced tomato growth and yield, opening a favorable scenario for large-scale application of this technology also in the Mediterranean area.
Comparison of a Response Surface Method and Artificial Neural Network in Predicting the Aerodynamic Performance of a Wind Turbine Airfoil and Its Optimization
Authors: Oh Sahuck
Published: September 2020

To find the optimal design for an engineering object, thousands of (or even more) simulations should be implemented to obtain the outcome data for the variously designed objects. However, repeating simulations this many times is impossible because a typical simulation is a computationally expensive task. Instead of conducting all the required simulations, a more efficient way is predicting the outcome from the approximation model, called the surrogate model. The response surface method (RSM) with polynomials and artificial neural network (ANN) are the most prominent methods in constructing a surrogate model in the engineering fields. In this study, the prediction accuracy of the surrogate models computed by using an RSM and ANN is compared with several datasets showing different complexities. This comparison is investigated by constructing the surrogate models in predicting aerodynamic performance of a wind turbine airfoil. In the current paper, it is verified that the prediction accuracy of the ANN-computed surrogate model is higher than the RSM-computed one when the datasets have a high level of complexity, but the opposite phenomenon is observed if the datasets have a low level of complexity. When the surrogate models with different accuracies are used to enhance the performance of a wind turbine airfoil, the surrogate model with a high level of accuracy produces the optimal design, showing a high performance improvement. The current study is expected to give guidance on how to properly choose between an RSM and ANN to construct a highly accurate surrogate model that can help in finding a design with a high performance improvement during the optimization process.

In the process of transcription initiation by RNA polymerase, promoter DNA sequences affect multiple reaction pathways determining the productivity of transcription. However, the question of how the molecular mechanism of transcription initiation depends on the sequence properties of promoter DNA remains poorly understood. Here, combining the statistical mechanical approach with high-throughput sequencing results, we characterize abortive transcription and pausing during transcription initiation by Escherichia coli RNA polymerase at a genome-wide level. Our results suggest that initially transcribed sequences, when enriched with thymine bases, contain the signal for inducing abortive transcription, whereas certain repetitive sequence elements embedded in promoter regions constitute the signal for inducing pausing. Both signals decrease the productivity of transcription initiation. Based on solution NMR and in vitro transcription measurements, we suggest that repetitive sequence elements within the promoter DNA modulate the nonlocal base pair stability of its double-stranded form. This stability profoundly influences the reaction coordinates of the productive initiation via pausing.

The use of insoluble bismuth salts, typically BiPO4, is known to be a viable alternative to classical Bi3+ ion electrochemical reduction for the preparation of bismuth film electrodes (BiFE) on screen-printed electrodes. The freshly prepared electrodes are indefinitely stable, and the active bismuth film is simply formed by in situ reduction. Two aspects are still to be investigated, namely the bismuth distribution on the working electrode and the possible residual presence of the counteranion, namely phosphate. High-vacuum techniques such as electron microscopy or spectroscopy, which are commonly employed for this purpose, cannot be safely used: the bismuth surface is well-known to reconstruct and recrystallize under the electron beam in vacuum. Here, we demonstrate the suitability and the effectiveness of laser ablation ICP-MS (LA-ICP-MS, a technique that vaporizes and analyzes the surface material under flowing helium at atmospheric pressure) for the characterization of BiFE. Fast and stable measurements of bismuth and phosphorous distribution are achieved with the advantage of a minimum alteration of the sample surface, avoiding possible interferences. This investigation evidenced how, upon reductive activation, the bismuth film is distributed with a radial symmetry and the phosphate counteranion is completely absent on the working electrode surface.

In this work, Sacha inchi (Plukenetia volubilis L.) residues were used as biomass feedstocks in catalytic upgrading pyrolysis with SBA-15, which is a substance synthesized from coal fly ash (CFA), using alkali fusion, followed by hydrothermal treatment (SBA-15-FA). The catalytic activity of fly ash-derived SBA-15 was investigated through the fast pyrolysis of Sacha inchi residues for upgrading the pyrolysis vapors using the analytical pyrolysis-GC/MS (Py-GC/MS) technique. The pyrolysis temperature was set at 500 °C and held for 30 s while maintaining the Sacha inchi residues to catalyst ratios of 1:0, 1:1, 1:5, and 1:10. In addition, the SBA-15s synthesized from chemical reagent and commercial SBA-15 were evaluated for comparison. The non-catalytic fast pyrolysis of Sacha inchi (SI) mainly consisted of fatty acids (46%), including chiefly linoleic acid (C18:2). Other compounds present were hydrocarbon (26%) and nitrogen-containing compounds (8.7%), esters (9.0%), alcohols (6.4%), and furans (3.6%). The study results suggested that the SBA-15-FA showcased a high ability to improve aliphatic selectivity (mainly C5–C20) and was found to be almost 80% at the biomass to catalyst ratio of 1:5. Moreover, the increase in catalyst contents affected the enhancement of hydrocarbons yields and tended to promote the deoxygenation reaction. Interestingly, the catalytic performance of SBA-15 derived from fly ash could be compared to that of the commercial SBA-15 in terms of producing hydrocarbon compounds as well as reducing oxygenated compounds.

The aim of this study was to compare the sensitivity of self-collected versus healthcare worker (HCW)-collected swabs for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) testing. Symptomatic individuals referred for SARS-CoV-2 testing were invited to provide mobile-phone video-instructed self-collected oropharyngeal and nasal samples followed by a HCW-collected oropharyngeal sample. All samples were sent for analysis to the same microbiology laboratory, and the number of SARS-CoV-2-positive participants in the two tests was compared. A total of 109 participants were included, and 19 participants had SARS-CoV-2-positive results. The diagnostic sensitivity of the self-collected and HCW-collected swabs was 84.2% and 89.5%, respectively, with an acceptable agreement, Cohens kappa 0.82, p < 0.001. Further, results from a questionnaire answered by the participants found that loss of smell as a self-reported symptom was a strong predictor for a SARS-CoV-2-positive test. In conclusion, we found that self-collected oropharyngeal and nasal swabs for SARS-CoV-2 testing can be reliable compared to HCW-collected oropharyngeal samples.
Coronary Microvascular Dysfunction and the Role of Noninvasive Cardiovascular Imaging
Authors: Ayub Muhammad Talha , Kalra Dinesh
Published: September 2020

Patients with coronary microvascular dysfunction (CMD) have significantly higher rates of cardiovascular events, including hospitalization for heart failure, sudden cardiac death, and myocardial infarction (MI). In CMD, several pathophysiological changes lead to functional and structural abnormalities in the coronary microvasculature, which disrupt the ability of the vessels to vasodilate and augment myocardial blood flow in response to increased myocardial oxygen demand, causing ischemia and angina. With the advent of more advanced non-invasive cardiac imaging techniques, the coronary microvasculature has been subjected to more intense study in the past two decades—this has led to further insights into the diagnosis, pathophysiology, treatment, prognosis and follow-up of CMD. This review will highlight and compare the salient features of the currently available non-invasive imaging modalities used in these patients, and discuss the clinical utility of these techniques in the workup and management of these patients.

This study aimed to establish the local diagnostic reference levels (LDRLs) of computed tomography pulmonary angiography (CTPA) examinations based on body size with regard to noise magnitude as a quality indicator. The records of 127 patients (55 males and 72 females) who had undergone CTPAs using a 128-slice CT scanner were retrieved. The dose information, scanning acquisition parameters, and patient demographics were recorded in standardized forms. The body size of patients was categorized into three groups based on their anteroposterior body length: P1 (14–19 cm), P2 (19–24 cm), and P3 (24–31 cm), and the radiation dose exposure was statistically compared. The image noise was determined quantitatively by measuring the standard deviation of the region of interest (ROI) at five different arteries—the ascending and descending aorta, pulmonary trunk, and the left and right main pulmonary arteries. We observed that the LDRL values were significantly different between body sizes (p < 0.05), and the median values of the CT dose index volume (CTDIvol) for P1, P2, and P3 were 6.13, 8.3, and 21.40 mGy, respectively. It was noted that the noise reference values were 23.78, 24.26, and 23.97 HU for P1, P2, and P3, respectively, which were not significantly different from each other (p > 0.05). The CTDIvol of 9 mGy and dose length product (DLP) of 329 mGy∙cm in this study were lower than those reported by other studies conducted elsewhere. This study successfully established the LDRLs of a local healthcare institution with the inclusion of the noise magnitude, which is comparable with other established references.

Information and communication technologies (ICT) are immersed in the teaching and learning processes. Specifically, educational robotics is a technology with great projection in learning spaces. This educational technology has revealed great potential in educational processes in the scientific literature. In this study, the Makey Makey device has been used to carry out a methodological contrast at the instructional level. The objective of this study is to verify if the use of the Makey Makey robotic device influences various psycho-social and educational dimensions in the subject of physical education. A quasi-experimental research design has been used in a sample of 177 students from secondary education. A questionnaire was used as the data collection instrument. The results show the ratings made by the control group students are lower than those of the experimental group in all dimensions, although there is no relationship of significance in all dimensions. This fact only occurs in motivation, teacher–student, student–content, collaboration, resolution, and teacher-rating dimensions. Conclusions show that the teaching method in which robotics is used leads to more success in the field of physical education if we compared it to the more conventional method. The outstanding data show the teaching–learning process has the highest influence on motivation, teacher–student, student–content, collaboration, resolution, and teacher rating.
Joint Message-Passing and Convex Optimization Framework for Energy-Efficient Surveillance UAV Scheduling
Authors: Jung Soyi , Kim Joongheon , Kim Jae-Hyun
Published: September 2020

In modern surveillance systems, the use of unmanned aerial vehicles (UAVs) has been actively discussed in order to extend target monitoring areas, even for an extreme circumstances. This paper proposes an energy-efficient UAV-based surveillance system that operates from two different sequential methods. First, the proposed algorithm pursues energy-efficient operations by deactivating selected surveillance cameras on the UAVs located in overlapping areas. For this objective, a message-passing based algorithm is used because the overlapping situations can be formulated using a max-weight independent set. Next, the unscheduled UAVs based on the message-passing fly to the charging towers to be charged. This algorithm computes the optimal matching between the UAVs and charging towers and the amount of energy allocation for the scheduled UAV-tower pairs. This joint optimization is initially formulated as non-convex, and it is then reformulated to be convex, which can guarantee optimal solutions. The proposed framework achieves the desired performance, as presented in the performance evaluation.
Penny Dreadful’s Queer Orientalism: The Translations of Ferdinand Lyle
Authors: Mustafa Jamil
Published: September 2020

Cultural expressions of Orientalism, the Gothic, and the queer are rarely studied together, though they share uncanny features including spectrality, doubling, and the return of the repressed. An ideal means of investigating these common aspects is neo-Victorian translation, which is likewise uncanny. The neo-Victorian Gothic cable television series Penny Dreadful, set mostly in fin-de-siècle London, employs the character Ferdinand Lyle, a closeted queer Egyptologist and linguist, to depict translation as both interpretation and transformation, thereby simultaneously replicating and challenging late-Victorian attitudes toward queerness and Orientalism.
