State-of-the-art of MW-level capacity oceanic current turbines
Authors: Boretti Alberto 
Published: August 2020

AbstractMarine hydrokinetic turbines of MW-level capacity for harvesting oceanic currents are here reviewed. The best design is 3-blades, open rotor, axial flow turbines, of similar design philosophy to wind turbines, which are anchored to the ocean floor. The best locations are those with the oceanic current resource of higher intensity and stability, non-excessive depth of the ocean floor, proximity to shore, and favorable topography. In these locations, marine hydrokinetic turbines may become competitive with other renewable energy alternatives. It is expected that such turbines will be installed and will start producing electricity, within the next decade, working with power coefficients, the ratio of electric power from the turbine to wind power, around 0.45, similarly to wind turbines. This will pave the road for further progress and significant uptake of technology so far of no impact on the global energy mix.

Published: August 2020

Abstract
Sorption distribution coefficient (Kd) of niobium-94 on minerals are an important parameter in safety assessment of intermediate-depth disposal of waste from core internals etc. The Kd of Nb on clay minerals in Ca(ClO4)2 solutions were, however, not successfully modeled in a previous study. The high distribution coefficients of Nb on illite in Ca(ClO4)2 solutions were successfully reproduced by taking Ca–Nb–OH surface species into account. Solubility of Nb was studied in Ca(ClO4)2 solutions and the results were reproduced by taking an aqueous Ca–Nb–OH complex species, CaNb(OH)6
+, into account in addition to previously reported Nb(OH)6
− and Nb(OH)7
2−. Based on this aqueous speciation model, the Ca–Nb–OH surface species responsible for the sorption of Nb on illite in Ca(ClO4)2 solutions was presumed to be X_OCaNb(OH)6. Although uncertainties exist in the speciation of aqueous Ca–Nb–OH species, the result of this study proposed a possible mechanism for high distribution coefficient of Nb on illite in Ca(ClO4)2 solutions. The mechanism includes Ca–Nb–OH complex formation in aqueous, solid and surface phases.
Protected Collateral Value: An Approach to Valuation of Commercial Properties for Loan Guarantees
Authors: Florêncio Lutemberg , de Alencar Claudio Tavares 
Published: August 2020

Abstract
The valuation of commercial properties for the guarantee of loans is extremely relevant for financial institutions, since it directly impacts the calculation of the loan to value ratio (LTV). However, despite the vast literature on the subject, the choice of methodological basis and the definition of the type of value to be employed are not pacified issues among researchers and practitioners. In this sense, the main objective of this paper is to present a methodological approach, as well as a suggestion of the type of value for the valuation of commercial properties bound collateral.
The main methods and types of values related to the valuation of bound collateral commercial properties are presented below. Next, we propose a refinement of the income method, based on the concept of the value of the investment opportunity and under the principle of value at risk. Finally, we promote a case study with data from the Brazilian market to illustrate the application of the proposed approach.
Based on the case study, it was evidenced that the valuation approach proposed in this paper, anchored in the potential of the income generation of the property, reduces the risk of exposure to banks’ credit.
Socio-Economic Factors as a Criterion for the Classification of Housing Markets in Selected Cities in Poland
Authors: Kokot Sebastian 
Published: August 2020

Abstract
Property prices, including, in particular, residential properties, vary across local markets. For example, according to the National Bank of Poland, in late 2018, the average unit price of an apartment on the secondary market stood at PLN 8,700 in Warsaw, 6,100 in Poznań, 4,800 in Szczecin, and 3,800 in Kielce and Zielona Góra. The level of prices on particular markets is affected by a variety of factors, primarily those of a social and economic nature. Earlier research work on the influence of such factors on the level of apartment prices was carried out on a random basis, and their results were also published in the Real Estate Management and Valuation journals (Kokot 2018). This article presents study results that help deepen and broaden such analyses, seeing as how the research work:

–
covers a period of 12 years (2006-2018),

–
proposes and then applies a city wealth synthetic measure (SMZM) in the analyses,

–
classifies cities according to the criterion of socio-economic factors and of average housing prices,

–
examines relationships within the groups of cities identified via classification.

The obtained results indicate that it is justified to consider the impact of socio-economic factors on housing prices precisely in the context of their appropriate classification. Moreover, they may be an indicative tool of identifying so-called comparable or parallel real property markets.

Published: August 2020

AbstractWith the development of high-throughput genotyping techniques, selection signatures in the genome of domestic pigs have been extensively interrogated in the last decade. The Duroc, a major commercial pig breed famous for its fast growth rate and high lean ratio, has not been extensively studied focusing on footprints of intensively artificial selection in their genomes by a lot of re-sequencing data. The goal of this study was to investigate genomic regions under artificial selection and their contribution to the unique phenotypic traits of the Duroc using whole-genome resequencing data from 97 pigs. Three complementary methods (di, CLR, and iHH12) were implemented for selection signature detection. In Total, 464 significant candidate regions were identified, which covered 46.4 Mb of the pig genome. Within the identified regions, 709 genes were annotated, including 600 candidate protein-coding genes (486 functionally annotated genes) and 109 lncRNA genes. Genes undergoing selective pressure were significantly enriched in the insulin resistance signaling pathway, which may partly explain the difference between the Duroc and other breeds in terms of growth rate. The selection signatures identified in the Duroc population demonstrated positive pressures on a set of important genes with potential functions that are involved in many biological processes. The results provide new insights into the genetic mechanisms of fast growth rate and high lean mass, and further facilitate follow-up studies on functional genes that contribute to the Duroc’s excellent phenotypic traits.

Published: August 2020

AbstractA 10-year-old female coati (Nasua nasua) was necropsied after an 8-day history of apathy, weight loss and dehydration. Gross changes consisted of multifocal to coalescing nodules ranging from 0.5 to 2.0 cm in diameter in the wall of the small intestine, adjacent to the mesentery and in the mesenteric lymph nodes. Histologically, neoplastic CD3-positive lymphocytes infiltrated all layers of the intestine, as well as the mesenteric adipose tissue and mesenteric lymph nodes. Based on the pathological and immunohistochemical findings, a diagnosis of intestinal T-cell lymphoma was made.

AbstractWorld has been suffering from pandemic caused by mysterious Coronavirus. The novel member of Coronaviridae causing COVID-19 disease is named as SARS-Cov-2. Its first case was reported in China by the end of 2019, but its exponential spread has wrapped entire globe, suspended and is penalizing mankind. A retrospective meta-analysis study showed that outbreaks of Middle East Respiratory Syndrome (MERS) and SARS-Cov-1 (Coronaviridae), influenza infection H1N1 and West-African Ebola caused lower mortality than this new pandemic COVID-19. Virus has appeared as a new human pathogen so to counter COVID-19 no specific vaccine, monoclonal antibodies have been manufactured till day. The outbreak of novel Coronavirus is treated with antimicrobial drugs but they have their own mild side effects. But the drastic spread of COVID-19 compels us also to use other ways to counter pandemic. Thus, passive immunization can be opted to hold back this mysterious virus. Passive immunization has been in use since early 20th century and showed its effectiveness against all previous infectious outbreaks including MERS and SARS-Cov-1 members of Coronaviridae. The review argues that convalescent plasma is an explicit option for containment of COVID-19 disease.

Elméleti háttérA nem öngyilkossági szándékkal történő önsértő viselkedés (pl. a saját test szándékos megvágása, megütése, megharapása) egyre növekvő mértékű magatartási és egészségügyi probléma a serdülők körében. Felmérésére többféle mérőeszköz született, de kevés olyan létezik, amely a jelenséget annak komplexitásában ragadja meg.CélVizsgálatunk célja a különböző önsértő viselkedésformákat több szempontból (pl. attitüdinális komponensek, kapcsolódó érzelmek, a háttérben meghúzódó okok) felmérő Kezelésközpontú Önsértés Kérdőív (Self-Injury Questionnaire-Treatment Related; SIQ-TR) bevezetése a hazai tesztállományba.MódszerekA mérőeszköz pszichometriai jellemzőit egy speciális populációban, 14 és 20 év közötti (átlagéletkor = 16,99 év; SD = 1,28 év) fiatal fogvatartottak körében mértük be. A 244 fős javítóintézeti minta 92,6%-a (n = 226) fiú volt. Az önsértéssel összefüggésben a negatív életeseményeket (Serdülő Életesemény Kérdőív) és az elkerülés-fókuszú érzelemregulációs mechanizmusokat (Tapasztalati Elkerülés Kérdőív; Serdülő Disszociatív Tapasztalatok Skála) is feltártuk.EredményekA javítóintézeti fiatalok 26,2%-a (n = 64) aktuálisan is végez önsértő viselkedést, 34,4%-uk (n = 84) esetében az önsértés az egy hónapnál korábbi élettörténetben jelent meg, a fennmaradó 39,3% (n = 96) saját bevallása szerint sohasem folytatott önsértést. Eredményeink szerint a kar- moláshoz és az ütéshez asszociálódik a legtöbb negatív érzelem, e két mód esetében a legerőteljesebb az arra irányuló figyelem, illetve azt követően a sebekről való öngondoskodás mértéke. Továbbá a karmolás és az ütés az a két önsértési mód, amelynek legjellemzőbb célja a negatív érzelmi állapotok csökkentése. A mintában a jelenleg és a korábban önsértők szignifikánsan több negatív életeseményt éltek át a megelőző fél évben a sohasem önsértőkhöz képest (F(2) = 9,16; p < 0,0001). Az aktuálisan önsértők jellemezhetők továbbá a legmagasabb disszociatív élményszinttel (F(2) = 7,82; p = 0,001) és kognitív inflexibilitással (F(2) = 6,58; p = 0,002). Következtetések: A Kezelésközpontú Önsértés Kérdőív magyar nyelvű változata (SIQ-TR-HU) hatékony eszköze a nem öngyilkossági szándékkal történő önsértés összetett vizsgálatának, ezzel összefüggésben célzott terápiás intervenciók megalapozását támogathatja.

Abstract
A new High Performance Liquid Chromatography–Photodiode Array Detector (HPLC–PDA) method has been developed for the chromatographic separation and simultaneous quantitative determination of nine bioactive compounds, i.e. four phenolic (gallic acid, ellagic acid, chebulinic acid, and tannic acid), two flavanoids (rutin and quercetin), two anthraquinones (sennoside A and B) and one oxygenated hydrocarbon (vitamin C) in a well-known Unani polyherbal formulation namely Itrifal's. Separation was accomplished on a C18 LiChrospher 100 column (5 µm, 250 × 4.6 mm) with a gradient elution and recorded at 254 nm. The results demonstrated that the proposed method is reproducible, accurate, economic, and suitable for the quality control of traditional polyherbal Unani formulations containing complex compounds with different structures such as Itrifals.

Published: August 2020

AbstractIn this work, Gas chromatograph-Mass Spectrometry (GC-MS) combined with solid phase micro-extraction technology was used to analyze the difference of volatile organic compounds (VOCs) in rapeseed oil of different grades, and the relationship between changes of VOCs and refining process were also investigated in order to construct a non-linear model, which could realize rapid and accurate discrimination of different grade rapeseed oils. 124 rapeseed oil samples with different grades were collected and analyzed by GC-MS technology and 55 VOCs were identified and selected as variables to characterize the internal quality information of rapeseed oils. Then, principal component analysis (PCA) method was used to extract useful features and reduce data dimensionality, and finally a discriminant model was built using linear discriminant analysis (LDA) algorithm. The correct recognition rate of sample set was close to 94.59%. The results showed that the proposed method is promising in discriminating different grades of vegetable oils. Besides, it provides a theoretical basis for studying the relationship between VOCs composition and vegetable oil quality.

AbstractBackground and aimsProblematic online social networking use is prevalent among adolescents, but consensus about the instruments and their optimal cut-off points is lacking. This study derived an optimal cut-off point for the validated Online Social Networking Addiction (OSNA) scale to identify probable OSNA cases among Chinese adolescents.MethodsA survey recruited 4,951 adolescent online social networking users. Latent profile analysis (LPA) and receiver operating characteristic curve (ROC) analyses were applied to the validated 8-item OSNA scale to determine its optimal cut-off point.ResultsThe 3-class model was selected by multiple criteria, and validated in a randomly split-half subsample. Accordingly, participants were categorized into the low risk (36.4%), average risk (50.4%), and high risk (13.2%) groups. The highest risk group was regarded as “cases” and the rest as “non-cases”, serving as the reference standard in ROC analysis, which identified an optimal cut-off point of 23 (sensitivity: 97.2%, specificity: 95.2%). The cut-off point was used to classify participants into positive (probable case: 17:0%) and negative groups according to their OSNA scores. The positive group (probable cases) reported significantly longer duration and higher intensity of online social networking use, and higher prevalence of Internet addiction than the negative group.ConclusionsThe classification strategy and results are potentially useful for future research that measure problematic online social networking use and its impact on health among adolescents. The approach can facilitate research that requires cut-off points of screening tools but gold standards are unavailable.

Published: August 2020

Introducción: para lograr relaciones caninas de clase I, se utilizan elásticos intermaxilares de clase II. El Sliding Jig es un aditamento que ejerce fuerza distal directa sobre el molar, potenciando el vector horizontal del elástico intermaxilar. Objetivo: Determinar y comparar, en un periodo de tres meses, el tipo y la cantidad de movimiento sagital y vertical del molar superior y del canino utilizando elásticos de clase II con y sin Sliding Jig.
Métodos: se realizó un ensayo clínico aleatorizado, no controlado sin cegamiento; se compararon 15 hemiarcadas tratadas con Sliding Jig, con 14 hemiarcadas tratadas solo con elásticos clase II. Los movimientos fueron evaluados por un investigador calibrado (ICC:>0,8), en una Tomografía Computarizada Cone Beam (CBCT) del maxilar superior inicial (T1) y una CBCT final (T2) a los tres meses de instalada la mecánica.
Resultados: las variables fueron resumidas en promedios y desviaciones estándar con un intervalo de confianza del 95 %; para la comparación de los resultados entre T1 y T2 se utilizó la prueba t-Student. Se encontró mayor distalización del molar superior y menor movimiento vertical del canino superior, en el lado de Sliding Jig comparado con el lado de solo elásticos, mostrando diferencias estadísticamente significativas (p<0,05). No se presentaron cambios significativos en los movimientos sagital y de inclinación del canino, ni en la inclinación del molar entre las dos mecánicas.
Conclusiones: el Sliding Jig fue más eficiente que los elásticos de clase II solos, en la distalización de los molares superiores y en el control de la extrusión del canino.
