SARS-CoV-2 samples may escape detection because of a single point mutation in the N gene
Authors: Ziegler Katharina , Steininger Philipp , Ziegler Renate , Steinmann Jörg , Korn Klaus , Ensser Armin
Published: October 2020

We found that a single nucleotide polymorphism (SNP) in the nucleoprotein gene of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from a patient interfered with detection in a widely used commercial assay. Some 0.2% of the isolates in the EpiCoV database contain this SNP. Although SARS-CoV-2 was still detected by the other probe in the assay, this underlines the necessity of targeting two independent essential regions of a pathogen for reliable detection.

Authors: Abbas Anwar Saad , Kadhum Mohammed Mansour
Published: September 2020

This research aims to shed light on the fire flame effect on some mechanical properties of SIFCON samples, such as compressive strength, flexural strength and modulus of elasticity and comparing the results with CEN design curve and CEB. Higher temperature resistance is one of the most important parameters affecting the durability and service life of the material. This study comprised of casting and testing SIFCON specimens with 6% fiber volume before and after exposure to elevated temperatures. Two fire exposure duration of 1 and2 hours were investigate. In addition to room temperature, Silica fume was used as a partial replacement (10%) by weight of cement. It was found from the results achieved that after exposure to high temperatures, compressive strength, flexural strength and elastic modulus decreased. The drastically reduction of compressive strength took place with increasing temperature.  The residual compressive strength, flexural strength and elastic modulus at 1010 °C were in the range of (58.4 to 80.1%), (81.6 to 78.7%) and (30.4 to 32.8%) respectively. The compressive strength test results of this study together with results obtained by other investigators were compared with CEB strength-reduction curve and that of CEN. It was noticed that the test results agreed with CEN design curve rather than with that of CEB.

Published: September 2020

In the curiosity forever improving fuel efficiency and emissions reduction, a new and highly   promising idea has found new life. HCCI (Homogeneous Charge Compression Ignition) technology has been around for a long time, but has recently received renewed attention and enthusiasm. An HCCI engine is a mix of both conventional spark-ignition and diesel compression ignition technology. The blending of these two designs offers diesel-like high efficiency without the difficulty   and expensive to deal with NOx and particulate matter emissions. For the above purpose the chicken fat oil   methyl ester – gasoline blend and chicken fat oil methyl ester - diesel blends are used in HCCI engine concept. The air and fuel mixture in various proportions are prepared externally by using a fuel vaporizer mounted in the intake pipe. Fuel injection is done by port fuel injector and the quantity is controlled by the electronic control unit (ECU). It can be observed from the above experimental work that the oil extracted from chicken fat can be a suitable alternative fuel to run diesel engine. Chicken fat oil methyl ester with the blend of 10% gasoline gives higher thermal efficiency than other fuel combinations with lower NOX and HC emissions.

UNREGISTERED MARRIAGE BETWEEN INDONESIAN CITIZENS AND FOREIGN CITIZENS WITH THE LEGAL PERSPECTIVE OF MARRIAGE IN INDONESIA
Authors: Muttaqin Muhammad Ngizzul
Published: October 2020

The practice of unregistered marriage between Indonesian citizens and foreign nationals always raises legal problems, both the law of marriage and the legal consequences of the marriage. This article aims to provide concrete legal solutions and steps to the practice of unregistered marriage between Indonesian citizens and foreign nationals. This study used literature research with qualitative descriptive methods, through a normative legal approach. The results show that unregistered marriage is a social symptom of modern society which always occurs in the practice of today’s society. Although unregistered marriage is not specifically regulated in the practice of mixed marriages, it often occurs and must be anticipated. The solution is that there are three legal options that can be taken: first, if the person concerned is domiciled in Indonesia and intends to become an Indonesian citizen, then s/he can register the marriage with the employee who registers the marriage and performs the marriage certificate according to the provisions. Second, if the person concerned is living abroad but wants to become an Indonesian citizen, then s/he can take legal steps by registering the marriage and marriage certificate at the Indonesian Embassy. Third, if the person concerned is domiciled and wants to become a resident of a foreign country, then the person concerned must take the legal route that has been determined in that country. Thus, family law in Indonesia can be adaptive and responsive to the dynamics of social change.

A importância da folga financeira nas empresas que investem em inovação
Authors: Cardozo Maria Luiza Piacenti , Santos David Ferreira Lopes
Published: October 2020

Este trabalho analisa a importância da folga financeira na caracterização das empresas industriais brasileiras que investem em inovação. A inovação nas empresas requer um processo robusto de financiamento cujos resultados são incertos. Assim, a folga financeira pode ser uma estratégia importante na caracterização das estratégias de inovação das empresas. Foram utilizadas todas as 106 empresas industriais listadas na B3 e feito um disclosure para identificar aquelas que investiam em inovação e aquelas que não faziam. Após a obtenção desses dados foi realizada uma análise fatorial como forma de resumir e reduzir os dados, para então verificar como as variáveis analisadas de folga financeira se agrupavam e se apresentam associação. Ademais, foi realizada uma análise de comparação de média e variância a fim de observar se de fato as empresas que apresentam gastos com inovação possuem uma maior folga financeira. Como resultado da análise fatorial, observa-se que as variáveis podem ser resumidas em quatro grupos, e estes são diferentes dos três grandes blocos (disponível, recuperável e potencial) que a literatura pressupõe. Como resultado da segunda análise, tem-se que as empresas que investem em inovação apresentaram menores padrões de variância para as variáveis de folga, isto é, são mais homogêneas e apresentam maiores níveis de folga

Authors: Carstensen Laura L. , Shavit Yochai Z. , Barnes Jessica T.
Published: September 2020

The COVID-19 pandemic is creating unprecedented, sustained, and unavoidable stress for the entire population, with older people facing particularly heightened risk of contracting the virus and suffering severe complications including death. The present study was conducted when the pandemic was spreading exponentially in the United States. To address important theoretical questions about age differences in emotional experience in times of crisis, we surveyed a representative sample of 945 Americans aged 18-76 and assessed the frequency and intensity of a range of positive and negative emotions. We also assessed perceived risk of contagion and complications from the virus, as well as personality, health, and demographic characteristics. Age was associated with relatively greater emotional well-being with and without controlling for perceived risk and other covariates. Findings extend previous research about age and emotion by demonstrating that older adults’ relatively better emotional well-being persists even in the face of prolonged stress.

Bu çalışmada 2019 yılı Aralık ayında ortaya çıkan ve 2020 yılı ortalarında etkileri halen devam eden koronavirüs salgınının Türkiye ekonomisi üzerindeki etkisi, hisse senedi borsa endeksi ve genel ekonomik faaliyetlerin düzeyi açısından analiz edilmiştir. Çalışmada hisse senetlerinin fiyat performansı olarak Borsa İstanbul BIST-100 endeksi, genel ekonomik faaliyetlerin düzeyini temsilen de Satın Alma Yöneticileri Endeksi kullanılmıştır. Koronavirüs krizinin etkilerinin hem diğer ülkelerde hem de ülkemizde zirvede olduğu 23 Mart-24 Nisan 2020 tarihleri arasındaki günlük veriler kullanılmıştır. Elde edilen bulgular, incelenen dönemde sosyal mesafe ve sokağa çıkma kısıtlaması uygulamasının genel ekonomik faaliyetlerin seviyesini -0,708 birim düşürdüğü ancak hisse senedi fiyatları üzerinde olumsuz bir etkide bulunmadığını göstermiştir. Genel olarak elde edilen sonuçlar, koronavirüs krizinin zirvede olduğu dönemde sokağa çıkma kısıtlaması, yurt içi seyahat kısıtlaması ve yurt dışı seyahat kısıtlaması uygulamaları ile para politikası kararlarının ve kamu harcamaları tutarının genel ekonomik faaliyetlerin seviyesiyle anlamlı bir ilişkide bulunduğunu ve etkilediğini göstermiştir. Söz konusu değişkenlerden yurt dışı seyahat kısıtlamasının BIST-100 hisse senedi borsa endeksinin kapanış fiyatını -0,058, en düşük fiyatını -0,038, para politikası kararlarının hisse senedi borsa endeksinin açılış fiyatını 0,043, en yüksek fiyatını 0,035, en düşük fiyatını 0,024, kapanış fiyatını 0,022 birim etkilediğini göstermiştir. Öte yandan, yurt içi seyahat hareketliliğine getirilen kısıtlamanın, para politikası kararlarının ve kamu harcamalarına ayrılan bütçe tutarının ekonomik faaliyetlerin düzeyi üzerinde olumlu bir etkisi olurken, açıklanan yeni COVID-19 vakaları sayısının hisse senedi endeksinin kapanış, açılış, en yüksek ve en düşük fiyatları ile pozitif yönde ilişkili olduğu görülmüştür. Bulguların sonucunda, para politikası kararlarının kısa dönemde COVID-19 pandemisinin etkilerini hafifletmede kamu harcamaları uygulamasından daha etkili olduğu belirlenmiştir.
The road less traveled: A cross-cultural study of the negative wording factor in multidimensional scales
Authors: Zhang Bo , Luo Jing , Chen Yueyang , Roberts Brent , Drasgow Fritz
Published: October 2020

Negatively worded items (NWIs) have been found to distort the hypothesized one-factor structure of many unidimensional scales and an additional negative wording factor is needed to achieve adequate model fit. However, little is known about impact, dimensionality, and correlates of the negative wording factor for multidimensional scales. Using responses to the Big Five Inventory-2 (BFI-2) administered to nationally representative samples of Germany, Spain, France, Japan, Poland, America, and England, the present study reported on a comprehensive cross-cultural examination of the impact, dimensionality, and external correlates of negative wording factors. We further investigated whether modeling a negative wording factor affects the factor structure and criterion-related validity. It was found that NWIs blurred the factor structure of the BFI-2 in non-English-speaking countries such that factors like agreeableness was not recovered, thus rejecting configural invariance. The results also strongly supported the idea that there was a general negative wording factor across subscales of the BFI-2 and this factor was consistently related to age, gender, educational attainment and life satisfaction across countries. Moreover, modeling a negative wording factor improved the factor structure of the BFI-2 and scalar invariance was achieved. Implications of these findings were discussed.
Walk This Way: Ingroup Norms Determine Voting Intentions for Those Who Lack Sociopolitical Control
Authors: Potoczek Anna , Bukowski Marcin , de Lemus Soledad , Jiménez-Moya Gloria , López Álvaro Rodríguez , Jasko Katarzyna
Published: October 2020

Even though taking part in elections is one of the most direct tools to influence the socio-political system, many people choose not to vote. Research shows that this problem is especially prevalent among those citizens who do not believe they have control over social and political issues, but the question remains as to what could encourage their voting behavior. We predicted that individuals who experience low levels of control can be more susceptible to ingroup norms regarding participation in political elections than those with a high sense of sociopolitical control. Across six studies we found consistent support for this hypothesis. Specifically, people who experience decreased sociopolitical control were more likely to vote when descriptive norms (measured or manipulated) were conducive to voting. The results have important theoretical and applied implications, illuminating the boundary conditions under which people deprived of control can still be motivated to participate in a political sphere.

Published: September 2020

Individuals generally revise their misconceptions when corrected with carefully designed educational materials. However, early reports suggest that correcting COVID-19 misconceptions may be especially challenging, which may be due to conflicts with individuals’ moral values and emotions. The present study explores the mechanisms and boundaries of correction effectiveness. Those highest in moral concerns for group cohesion or for individual freedoms were more likely to affectively or cognitively reject corrective information. Corrections of COVID-19 misconceptions should be carefully framed to connect with the morality of recipients and anticipate their emotional and cognitive reactions.

Published: October 2020

The current research tests the links between emotion regulation and psychological and physical health during the COVID-19 pandemic. In Study 1, parents (N = 365) who had reported on their psychological and physical health prior to the pandemic completed the same health assessments along with their use of emotion regulation strategies when confined in the home with their school-aged children during a nationwide lockdown. In Study 2, individuals (N = 1,607) from a nationally representative panel study completed similar measures of psychological and physical health and use of emotion regulation strategies 1-year prior to the lockdown and then again during the lockdown. Accounting for pre-pandemic psychological health, greater rumination and emotional suppression were independently associated with poorer psychological health (greater depressive symptoms and psychological distress, lower emotional and personal well-being), even when controlling for the emotional challenges of the pandemic (emotion control difficulties, perceived support; Studies 1 and 2) and a range of demographic covariates (Study 2). Greater rumination was also associated with greater fatigue in both studies, but greater rumination and emotional suppression were only independently associated with poorer perceptions of physical health in Study 2. The results for cognitive reappraisal were mixed; positive associations with personal well-being and general health only emerged in Study 2. The results provide evidence that key models in affective science help explain differences in psychological and physical health within the throes of a real-world demanding context, and thus offer targets to help facilitate health and resilience during the pandemic (and other crises).

Published: October 2020

The study assesses the likely consequences of COVID-19 in the forest sector of Nepal, focusing on timber production and rural livelihoods. The study conducted telephone interviews along with a review of the secondary source of information and consultations. The timber production in 2020 is likely to decrease by 80% compared to previous years, resulting in a monetary loss of NRs 647.0 million. Furthermore, local community will lose 147,447 days of employment, amounting NRs 117.9 million. This will make livelihoods of the people more vulnerable. Returning of youths from abroad can further escalate biodiversity threats. Timber import is likely to increase in the country, thus impacting on local level employment opportunities. Both long-term and short-term strategies are necessary to revive the timber production and rural livelihoods, where priority should be on increasing investment in the forestry sector. However, public-sector investment is declining. Hence there is a need to expand conservation finance portfolios to incentivise rural people on timber production and achieve synergies between conservation and livelihood outcomes.
Nepali Migrant Workers amid Covid-19 in Major Destination Countries: A Human Security Approach
Authors: Bhattarai Gaurav , Baniya Jeevan
Published: October 2020

The global outbreak of novel corona virus has exposed a severe crisis and threat in the human security of the thousands of Nepali workers abroad. It has challenged a rather limited conception and understanding of security in the context of Nepali migrant workers and has led to rethink policies and plans about safe, dignified, and managed migration. This article seeks to identify the situations of Nepali migrant workers in major destinations such as the Persian Gulf and Malaysia and discusses the factors that shape a sense of insecurity/security and dignity among them. In this article, first, we argue that Nepali migrant workers have become vulnerable due to the challenges and risks facing them related to infection and deaths, loss of jobs and income, lack of safe and dignified repatriation, no access to essential services including food, accommodation and health, unsafe working and living situation and discrimination and ill-treatments. Second, we highlight that the government of Nepal needs to effectively regenerate and exercise its labour diplomacy to make the destination countries more accountable to their responsibilities towards labour migrants and their human rights, and equally tailor its development policies to create adequate and decent opportunities within the country.

Published: September 2020

Two Generation III+ VVER-1200 units are planned to be built in Hungary. Investigation of core improvements made for the new reactor type has been done by the vendors. However, appropriate independent calculation tools are advantageous for the users, among others, for strengthening the safety level. Recently several new VVER reactors have been commissioned; among them three VVER-1200 units. To determine experimentally neutron-physics characteristics of those units, similar startup test programs were performed and extended with some new, unconventional measurements. Several experiments from the physical startup of a VVER-1200 were published recently. This contribution summarizes the experience gathered at MTA EK with the newly developed KARATE-1200 code system on the basis of the reactivity measurements obtained from the literature.

Cannabis sativa L is one of the most used drugs in the world. Information about the plant’s age and storage can help forensic scientists to identify and to track samples. The ratio between the cannabinoids tetrahydrocannabinol (THC) and cannabinol (CBN) has been related to the degradation of cannabis with time. Thus, this study aimed to test Multivariate Image Analysis (MIA) to evaluate cannabis extracts concerning its colors. Initially, 52 samples of Cannabis sativa L. extracts were analyzed by Gas Chromatography coupled to Flame Ionization Detector (GC/FID) to quantify THC and CBN. Afterwards, the extract samples were photographed and analyzed by two different multivariate analysis tools: ChemoStat®, a free chemometrics software, and PhotoMetrix PRO®, an app for mobile devices. Using exploratory analysis of principal component analysis (PCA) and hierarchical cluster analysis (HCA). It was observed that the more intense the color for an extract, the higher concentration of THC and CBN it has, while the lighter color extracts correspond to samples with no THC. The results suggest to propose a simple method for previous clustering of samples that may precede chromatographic analyzes, assist in chemical profile studies or simply aggregate samples of similar profiles for analyzed together.

Published: October 2020

Li4Ti5O12 (LTO) anode doped with Al ions with varying concentrations (Al = 0; 0.005; 0.015; 0.03; 0.045) was successfully synthesized using the sol-gel method. Al-doped LTO samples were obtained through the sintering of gel at 850oC for 4 hours under a normal atmosphere. Electrochemical performance such as charge-discharge capacity and diffusion coefficient were characterized using an automatic battery cycler. The cells consist of electrode sheets (LTO doping Al) as a working electrode, lithium metal as the counter electrode, Celgard film as the separator, and LiPF6 as an electrolyte. Cyclic voltammetry test results show that a greater scan rate results in decreased capacity and greater polarization voltage. In addition, an increase in concentrations used in Al doping on LTO causes capacity, and the diffusion coefficient tends to decrease.
Lesión renal aguda inducida por medio de contraste
Authors: Arias Leal María Luisa , Ramírez Vargas Xinia , Madrigal Zamora Sofía
Published: October 2020

La lesión renal aguda se puede definir mediante diversos criterios como, un aumento de la creatinina sérica 1.5 veces sobre el valor de referencia posterior a la utilización de medios de contraste. Los medios de contraste son solutos de diferentes osmolalidades, los cuales se utilizan para realizar diversos procedimientos médicos. La incidencia de este padecimiento varía dependiendo de diversos factores tales como factores propios de cada paciente, dosis de medio de contraste utilizada, vía de administración del contraste, entre otros. Los mecanismos fisiopatológicos que intervienen en la lesión renal aguda son multifactoriales y aún no están completamente identificados, por tanto, es importante realizar una buena historia clínica y examen físico para identificar esta población en riesgo y las medidas del caso como la nefroprotección. A su vez es importante para todos los médicos conocer los fármacos potencialmente nefrotóxicos y su debido manejo con los pacientes en riesgo, ya que una vez establecida la nefropatía inducida por contraste no existe un tratamiento efectivo y los pacientes pueden evolucionar a diversas complicaciones empeorando el pronóstico a corto y largo plazo.

Published: October 2020

Background: Most cardiovascular troubleshot ultimately result of endothelial dysfunction-induced
hypertension, an intractable problem in modern medicine. Fagara tessmannii, a shrub of the African
rainforests found in Cameroon is traditionally used to treat heart diseases and hypertension. This study
aimed to evaluate the preventive effects of the aqueous extract of F. tessmannii (AEFT) on arterial
hypertension induced by NG-Nitro-L-arginine-methyl ester (L-NAME).
Methods: Male Wistar rats received saline (5 mL.kg-1
, intraperitoneally) or L-NAME (25 mg.kg-1
;
intraperitoneally), L-NAME + AEFT (100 or 200 mg.kg-1
; orally) or captopril (20 mg.kg-1
; orally) for three
weeks. Then, blood and pulse pressures (BP and PP), heart rate, lipid profile, kidney, liver and heart function
markers and oxidative status were evaluated.
Results: AEFT (100 and 200 mg.kg-1
) prevented the increase in BP (p < 0.001), PP (p < 0.01), and heart
rate (p < 0.05) induced by L-NAME. The extract has suppressed the decline of weight gain, visceral fat and
triglyceridemia, decreased total cholesterol, increased HDL-cholesterol, and significantly reduced
(p < 0.001) atherogenic and coronary risk indicators. AEFT also improved the liver, kidney and heart
markers, nitrites levels and prevented TBARS enhancement as compared to the hypertensive group. The
remodeling of the media and fibrosis process in coronaries were also prevented by the extract.
Conclusion: These results suggest that AEFT can prevent endothelial dysfunction-induced hypertension,
dyslipidemia and associated atherogenic risks, and oxidative stress induced by L-NAME.
A review of the genus Chrastoblatta Saussure et Zehntner, 1895 (Dictyoptera: Ectobiidae: Blattellinae)
Authors: Anisyutkin L.N.
Published: October 2020

This paper gives a review of the insufficiently studied genus Chrastoblatta Saussure et Zehntner, 1895. The genus Chrastoblatta was described from Madagascar (environs of Antananarivo) and includes two species: Ch. tricolor Saussure et Zehntner, 1895 and Ch. dimidiata (Saussure, 1863). This contribution is based on the study of a series of paralectotypes of Ch. tricolor and syntypes of Ch. dimidiata from The Muséum d’histoire naturelle in Geneva. Additional specimens of Ch. tricolor were found in the collection of the Zoological Institute of the Russian Academy of Sciences in Saint Petersburg. Detailed morphological description of the type species, Ch. tricolor, is given. Particular attention is paid to the structure of the male and female genitalia, which are described for the first time. Chrastoblatta dimidiata is briefly described due to insufficient and damaged material, but it is probably closely related to the type species. The genus Chrastoblatta is characterized by a peculiar structure of the wide and flat head, hind tibiae with concavity at the apex, a distinctly reduced 4th segment of the tarsi, an asymmetrical hypandrium, and robust, curved styli. The presence of not inverted genitalia suggests the placement of Chrastoblatta in the subfamily Blattellinae. At the present time, the differential diagnosis of the genus Chrastoblatta based on characters of the male and female genitalia cannot be compiled due to insufficient knowledge of other Madagascan ectobiid.
