Quantum mechanics of a particle on a torus knot: Curvature and torsion effects
Authors: Biswas D. , Ghosh S.
Published: December 2020

In this paper, we study the subtle effect of constraints on the quantum dynamics of a point particle moving on a non-trivial torus knot. The particle is kept on the knot by the constraints, generated by curvature and torsion. In the Geometry-Induced Potential (GIP) approach, the Schrödinger equation for the system yields new results in particle energy eigenvalues and eigenfunctions, in contrast with existing results that ignored curvature and torsion effects. Our results depend on Γ, parameter that characterizes the global features of both the embedding torus and, more interestingly, the knottedness of the path.
High-Frequency Jet Ventilation for a Patient With Tracheomediastinal Fistula, Tension Pneumomediastinum, and Pneumothorax: A Case Report
Authors: Chan Chi Ho , Tan Elizabeth S. J. , Loh Kenny W. T. , Ong Sharon G. K.
Published: December 2020

Tracheomediastinal fistula (TMF) is an uncommon condition and carries a high mortality. We report the anesthetic management of a patient with TMF using stent insertion via rigid bronchoscopy. The TMF was a complication of double-lumen endotracheal tube insertion resulting in a tension pneumomediastinum. Initial intraoperative attempts to ventilate the lungs and overcome the air leak with high gas flow of 45 L/min via the side port of the bronchoscope resulted in a pneumothorax. This case report demonstrates that high-frequency jet ventilation can minimize the air leak and avoid barotrauma during anesthesia for TMF repair.

Published: December 2020

Echinococcosis, also known as hydatid disease, is a common parasitic human infestation found in sheep-breeding areas. It is caused by the larvae stage of Echinococcus granulosus, and cysts develop mostly in the lungs and the liver. Cardiac involvement is unusual and silent until acute complications or a fatal outcome occurs. Herein, we report an autopsy case of a young healthy adult who died suddenly. The autopsy revealed an external bulging on the right heart ventricle outlet with a fluid-filled cystic cavity discovered on sectioning. Dissection of other organs did not reveal other cyst locations. Histological examination ascertained the diagnosis of hydatid cyst, and death was attributed to cardiac arrhythmias. Pathologists should keep in mind that hydatid cysts can develop anywhere in the body. Solitary cardiac cyst is rare and can simulate a “silent bomb”. Unfortunately, sudden death remains the frequent manner of revelation of this disease in endemic areas.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and has been a global public health concern. Co-infection of SARS-CoV-2 and other respiratory syndrome has been rarely reported.

We report coinfection of SARS-CoV-2 and 2009 H1N1 Influenza strain in a French patient with pneumonia leading to acute respiratory distress syndrome.  The patient also had a medical history of pulmonary sarcoidosis with a restrictive ventilatory syndrome, which would be a supplementary risk to develop a poor outcomes. This case highlights the possible coinfection of two severe SARS-CoV-2 and influenza H1N1 viruses, which presents a higher risk to extend the care duration. The overlapping clinical features of the two respiratory syndromes is a challenge, and awareness is required to recommend an early differential diagnosis.

Published: December 2020

Background: Caesarean sections have become the most popular method for delivering twin babies because of the safety concerns associated with a natural birth. This study aims to identify the maternal characteristics and obstetric parameters that serve as risk factors influencing caesarean delivery in twin pregnancies by comparing women delivering via caesarean section and vaginal birth.

Methods: A retrospective chart review design was used to analyse 47 women with multiple pregnancies from the medical records at a primary referral hospital in East Java, Indonesia. Women delivering vaginally were then compared with women who underwent a caesarean section to identify any differences between the groups.

Results: More women delivered by caesarean section than by vaginal birth. In this study, women were more likely to undergo a caesarean section if they had a previous history of undergoing a caesarean section or if there were no foetal malpresentations during their pregnancy. There was a significant difference in maternal age between groups. We found that foetal malpresentation did not significantly increase the likelihood of caesarean delivery in women with multiple pregnancies.

Conclusions: The percentage of multiple pregnancies delivered via caesarean section is quite high. Similar to previous studies, we identified a few factors including foetal malpresentation and labour augmentation that did not significantly increase the risk of caesarean delivery. However, we suggest that there is more than one reason responsible for the increase in caesarean sections in multiple pregnancies.
Stratigraphy and U–Pb Zircon–Titanite Geochronology of the Aley Carbonatite Complex, Northeastern British Columbia: Evidence for Antler-Aged Orogenesis in the Foreland Belt of the Canadian Cordillera
Authors: McLeish Duncan F. , Johnston Stephen , Friedman Richard , Mortensen James
Published: December 2020

The tectonic significance and age of carbonatite intrusions in the central Foreland Belt of the Canadian Cordillera are poorly constrained. Recent work has demonstrated that one of these carbonatite intrusions, the Aley carbonatite, was emplaced as a syn-kinematic sill, coeval with a major nappe-forming tectonic event. Determining the age of the Aley carbonatite thus provides a means of directly dating syn-tectonic magmatism. Attempts at dating carbonatite units failed due to low U–Pb content in sampled zircon; however, a U–Pb titanite age of 365.9 ± 2.1 Ma was obtained from the Ospika pipe, an ultramafic diatreme spatially and genetically related to the carbonatite. This U–Pb titanite age is further supported by respective 40Ar/39Ar phlogopite ages of 359.4 ± 3.4 Ma and 353.3 ± 3.6 Ma for the pipe and a spatially associated lamprophyre dyke. We interpret the Late Devonian U–Pb titanite age of the Ospikapipe to be the minimum possible age of the carbonatite and syn-magmatic nappe-forming tectonic event. The maximum possible age of the carbonatite is constrained by the Early Devonian age of the Road River Group, the youngest strata intruded by carbonatite dykes and involved in the nappe-forming event. Our dating results for the Aley carbonatite closely correlate with U–Pb zircon and perovskite ages obtained for the Ice River carbonatite complex in the central Foreland Belt of the southern Canadian Cordillera, and support the interpretation of carbonatite intrusions of the western Foreland Belt as genetically linked components of an alkaline-carbonatitic magmatic province. Structural, stratigraphic, and geochronological data from the Aley area indicate that deformation was similar in style to, and coeval with, structures attributable to the Antler orogeny, and are consistent with the Antler orogen having extended the length of the Cordilleran margin from the southern United States to Alaska.

Published: December 2020

Este artigo tem por objetivo relatar e discutir a experiência de uma proposta de ensino com memes aplicada no Colégio Estadual Odorico Tavares, durante o período de Estágio Supervisionado II de Língua Portuguesa, realizado no curso de Letras da Universidade federal da Bahia. A metodologia utilizada foi o relato de experiência, descritivo, reflexivo e interpretativo. Os memes foram escolhidos como proposta de ensino por serem textos contemporâneos que possuem semioses distintas, tais como: imagem, cor, gestos, texto escrito etc., bem como devido à proximidade dos discentes com esses textos. A proposta de ensino teve como premissa proporcionar a aprendizagem do conteúdo a partir de elementos da própria realidade dos alunos. Dessa forma, pretende-se discutir a importância de o professor trabalhar com textos multimodais em sala de aula e “contemplar também os novos letramentos, essencialmente digitais”, conforme orienta a Base Nacional Comum Curricular (20178). Nesse sentido, serão abordados os conceitos de memes e de textos multimodais, o relato da experiência dessa proposta de ensino no colégio Estadual Odorico Tavares, a importância de ensinar o conteúdo a partir da realidade dos discentes e as contribuições da proposta de ensino com memes não somente para o ensino de língua portuguesa, mas para a compreensão de fenômenos socioculturais, os quais estão imbricados na língua, no discurso. Pretende-se com este estudo evidenciar a importância do trabalho com os gêneros digitais na escola, explorando a “análise de elementos discursivos, composicionais e formais de enunciados nas diferentes semioses” (BNCC, 2018), visando proporcionar a esses jovens reflexões, interpretações e compreensões de múltiplas linguagens.
Research on the performance of the spin Hall effect of light based on a magnetized plasma layered structure
Authors: Wang Pengxiang , Wan Baofei , Wang Qianyu , Zhang Haifeng , Zhang Dan
Published: December 2020

In this paper, a new, to the best of our knowledge, engineering structure is proposed to explore the sensitivity of the performance of the spin Hall effect of light (SHEL) to external parameters. The structure is composed of a glass layer, air layer, and middle layer, which is made up of a magnetized plasma layered structure. The simulation results show that all of the plasma frequencies, the frequency of incident light, the number of magnetized plasma layers, and the magnetic field distribution do make a difference to the performance of the SHEL. In the calculation process, the transfer matrix method is used to obtain reflection coefficients and then obtains the lateral displacement. The computed results demonstrate that the horizontal displacement of SHEL gets to the largest value when the plasma frequency is quadruple

, and the horizontal displacement trails off while the turning point veers to the right with the augmentation of the frequency of incident light. Furthermore, the horizontal displacement of SHEL will suffer from an increasing number of magnetized plasma layers. It is also confirmed that the magnetic field distribution has some effects on the behavior of SHEL. Through these findings, certain parameters can be measured by measuring the angle of shift and the size of the horizontal displacements, such as the refractive index. Thus, our research is of great help to some applications, such as sensors.
Retrieval of molecular alignment and identification of multiple-orbital contribution by using polarized high harmonics from aligned N2 molecules
Authors: Guo Xiaoli , Jin Cheng , He ZiQiang , Yao Jinping , Zhou Xiao-Xin , Cheng Ya
Published: December 2020

With the parallel and perpendicular components of high harmonics generated by using aligned N2 molecules, we propose a method to retrieve the alignment distribution induced by the aligning laser based on the quantitative rescattering theory. And the intensity of pump laser and gas temperature can be precisely determined as well. We find that the intensity ratio between two harmonic components is very sensitive to the inclusion of multiple-orbital contribution in the theory. We thus suggest that it could be used to identify the interference from inner orbitals by tuning input laser power or extending the spectral region of high harmonics.

Published: December 2020

A novel and effective simultaneous recording method, to the best of our knowledge, is proposed for improving the diffraction efficiency and uniformity of full-color holographic optical elements (HOE) using the Bayfol HX102 photopolymer. To improve the diffraction efficiency of a full-color HOE, it is important to find the optimal recording beam intensity taking into account the initial and late responses of the medium. The range of optimal beam intensity for recording full-color HOE can be found experimentally by analyzing the inhibition period and response characteristics of the recording medium for three wavelengths. Through this method, a full-color HOE with an average diffraction efficiency of about 56.81% and a standard deviation of about 1.7% was implemented in a single layer photopolymer.
Transmission across the water-air interface: resolving the impact of multiple interactions at the sea surface
Authors: McKee David , Piskozub Jacek
Published: December 2020

A series of Monte Carlo and HydroLight radiative transfer simulations are used to demonstrate that the traditional form of the Fresnel transmission across the water-air interface is accurate. This contradicts assertions to the contrary in a recent paper [Opt. Express 25, 27086 (2017)10.1364/OE.25.027086] that suggested that the impact of multiple surface interactions had previously been ignored and that the transmission factor was dependent upon the turbidity of the water.
Comprehensive investigation on the power scaling of a tapered Yb-doped fiber-based monolithic linearly polarized high-peak-power near-transform-limited nanosecond fiber laser
Authors: Huang Long , Ma Pengfei , Su Rongtao , Lai Wenchang , Ma Yanxing , Zhou Pu
Published: December 2020

An all-fiberized linearly polarized nanosecond master oscillator power amplifier based on polarization-maintaining large-mode-area Yb-doped tapered double cladding fiber (T-DCF) is comprehensively investigated. Firstly, excellent performance of the Yb-doped T-DCF for suppressing nonlinear effects, including stimulated Brillouin scattering (SBS) effect and spectral broadening effects, is experimentally demonstrated and qualitatively analyzed. An SBS-free average output power of 8.8 W is obtained under pulse duration of 3.8 ns and repetition frequency of 80 kHz, with peak power of ∼30 kW, pulse energy of 110 µJ and nearly transform-limited linewidth of < 283.8 MHz respectively. The polarization extinction ratio is > 16 dB and near-diffraction-limited beam quality with M2 factor of 1.2 is maintained at the maximal output power. Moreover, the discussion on the optimization of the system for further power scaling is carried out based a nonlinear dynamic model that is capable of simultaneously evaluating the time-domain and frequency-domain evolution properties of the narrow-linewidth linearly-polarized pulsed laser, and meaningful conclusion is obtained.
Imaging metasurfaces based on graphene-loaded slot antennas
Authors: Goldstein Jordan A. , Englund Dirk R.
Published: December 2020

Spectral imagers, the classic example being the color camera, are ubiquitous in everyday life. However, most such imagers rely on filter arrays that absorb light outside each spectral channel, yielding ∼1/N efficiency for an N-channel imager. This is especially undesirable in thermal infrared (IR) wavelengths, where sensor detectivities are low. We propose an efficient and compact thermal infrared spectral imager comprising a metasurface composed of sub-wavelength-spaced, differently-tuned slot antennas coupled to photosensitive elements. Here, we demonstrate this idea using graphene, which features a photoresponse up to thermal IR wavelengths. The combined antenna resonances yield broadband absorption in the graphene exceeding the 1/N efficiency limit. We establish a circuit model for the antennas’ optical properties and demonstrate consistency with full-wave simulations. We also theoretically demonstrate ∼58% free space-to-graphene photodetector coupling efficiency, averaged over the 1050 cm−1 to 1700 cm−1 wavenumber range, for a four-spectral-channel gold metasurface with a 0.883 µm by 6.0 µm antenna pitch. This research paves the way towards compact CMOS-integrable thermal IR spectral imagers.

Published: December 2020

Objective

The objective of this study was to evaluate the relationship between concurrent physician-based mental health services, all-cause mortality, and acute health service use for individuals enrolled in Opioid Agonist Treatment in Ontario, Canada.

Methods

A cohort study of patients enrolled in opioid agonist treatment in Ontario was conducted between January 1, 2011, and December 31, 2015, in Ontario with an inverse probability of treatment weights using the propensity score to estimate the effect of physician-based mental health services. Treatment groups were created based on opioid agonist treatment patients’ utilization of physician-based mental health services. Propensity score weighted odds ratios were calculated to assess the relationship between the treatment groups and the outcomes of interest. The outcomes included all-cause mortality using data from the Registered Persons Database, Emergency Department visits from the National Ambulatory Care Database, and hospitalizations using data from the Discharge Abstract Database. Encrypted patient identifiers were used to link across databases.

Results

A total of 48,679 individuals in OAT with mental disorders. Opioid agonist treatment alone was associated with reduced odds of all-cause mortality (odds ratio (OR) 0.4, 95% confidence interval (CI) 0.3–0.4). Patients who received mental health services from a psychiatrist and primary care physician while engaged in OAT, the estimated rate of ED visits per year was higher (OR = 1.3, 95% CI 1.2–1.4) and the rate of hospitalizations (OR = 0.5, 95% CI 0.4–0.6) than in the control group.

Conclusion

Our findings support the view that opioid agonist treatment and concurrent mental health services can improve clinical outcomes for complex patients, and is associated with enhanced use of acute care services.
Does learning history shape the associability of outcomes? Further tests of the outcome predictability effect
Authors: Liu Wei , Livesey Evan J. , Lachnit Harald , Don Hilary J. , Thorwart Anna
Published: December 2020

In recent years, several studies of human predictive learning demonstrated better learning about outcomes that have previously been experienced as consistently predictable compared to outcomes previously experienced as less predictable, namely the outcome predictability effect. As this effect may have wide-reaching implications for current theories of associative learning, the present study aimed to examine the generality of the effect with a human goal-tracking paradigm, employing three different designs to manipulate the predictability of outcomes in an initial training phase. In contrast to the previous studies, learning in a subsequent phase, when every outcome was equally predictable by novel cues, was not reliably affected by the outcomes’ predictability in the first phase. This lack of an outcome predictability effect provides insights into the parameters of the effect and its underlying mechanisms.
Infant-adult synchrony in spontaneous and nonspontaneous interactions
Authors: Cuadros Zamara , Hurtado Esteban , Cornejo Carlos
Published: December 2020

Infant-adult synchrony has been reported through observational and experimental studies. Nevertheless, synchrony is addressed differently in both cases. While observational studies measure synchrony in spontaneous infant-adult interactions, experimental studies manipulate it, inducing nonspontaneous synchronous and asynchronous interactions. A still unsolved question is to what extent differ spontaneous synchrony from the nonspontaneous one, experimentally elicited. To address this question, we conducted a study to compare synchrony in both interactional contexts. Forty-three 14-month-old infants were randomly assigned to one of two independent groups: (1) the spontaneous interaction context, consisting of a storytime session; and (2) the nonspontaneous interaction context, where an assistant bounced the infant in synchrony with a stranger. We employed an optical motion capture system to accurately track the time and form of synchrony in both contexts. Our findings indicate that synchrony arising in spontaneous exchanges has different traits than synchrony produced in a nonspontaneous interplay. The evidence presented here offers new insights for rethinking the study of infant-adult synchrony and its consequences on child development.

Published: December 2020

Background and Aim: Wild mammals are among the most threatened species of the world in large part due to human activity. In this work, we used the method of partial least squares-path modeling associated with a geographic information system to analyze the impact of anthropogenic pressures on the mortality of wild mammals.

Materials and Methods: We collected the data related to the cause of death of native wild mammals admitted to the Wildlife Rehabilitation Centre of Parque Biológico de Gaia in Northern Portugal, during 10 years (2008-2017).

Results: A total of 359 animals from 42 municipalities (rural and urban areas) were included in the study. The main cause of death was of traumatic origin. From the anthropogenic pressures included in the study, water reservoirs, small companies, and residential buildings were the ones that contributed the most to increase the mortality of traumatic and nontraumatic origin. This relation of cause-effect (mortality-anthropogenic pressures) was supported by the high coefficients of determination obtained (R2>0.8).

Conclusion: The present results allow a general view on the reality of mammal's mortality in Northern Portugal. Furthermore, it could also constitute a valuable tool for the conservation of wild mammals in those areas.
Dialógus a változásmenedzsmentben: A megértés, az együtt-cselekvés és a változás feltételei és lehetőségei az európai légiforgalmi irányításban

Kutatóként a fókuszpontom alapvetően a változásmenedzsmentből indult. Megnéztem, milyen típusú változásokkal foglalkoznak az ismert változásmenedzsment elméletek. Arra a megállapításra jutottam, hogy minél komplexebb változásokra adnak megoldásokat, annál inkább lesz központi elem ezekben a modellekben a vezetők és munkavállalók közötti partnerség, együttműködés, és dialógus. Részletesebben megvizsgáljam, az elméletek pontosan mit értenek dialógus alatt. A változásmenedzsment elméletek dialógus – koncepciójának feltárásával párhuzamosan kiléptem a változásmenedzsment és úgy általában a menedzsment diszciplína keretei közül, és megvizsgáltam, más tudományterületek mit értenek dialógus alatt. A filozófia, a teológia, az irodalomtudomány és a kulturális antropológia (szociológia) dialógus-elméleteit hívtam segítségül, és ezeknek egyfajta összeolvasásával felállítottam egy dialógus-modellt. Később elemeztem, hogy ez a dialógus modell milyen módon viszonyul az ismert változásmenedzsment elméletek dialógus-koncepcióihoz. A kutatásom empirikus szakaszában azt vizsgálom, mindez hogyan történik a szervezeti valóságban. Fontosnak tartottam olyan kutatási terepet választani, ahol a téma (változás, változásmenedzsment, dialógus) aktuális, kiemelkedő jelentőséggel bír. Így esett a választásom az európai légiközlekedési iparágra, azon belül is a légiforgalmi irányításra.

Os leites fermentados e os prebióticos são considerados alimentos funcionais e têm despertado cada vez mais o interesse das indústrias. Este estudo objetivou avaliar a influência da farinha de polpa de banana verde (FPBV) e inulina na multiplicação de Streptococcus thermophilus durante o processo fermentativo e por um período de 28 dias de armazenamento do leite fermentado. Os ensaios foram realizados em três tratamentos com três repetições, sendo a formulação A constituída de leite sem adição de FPBV e inulina, a formulação B contendo leite e FPBV e a formulação C contendo leite, FPBV e inulina. A FPBV apresentou 14,25% de umidade, 4,01% de cinzas, 2,28% de proteínas e 1,38% de extrato etéreo. Os valores de pH inicial das formulações A, B e C foram 7,30, 7,14 e 7,15, respectivamente, e após 4 horas atingiram os valores 4,57, 4,73 e 4,66, respectivamente. Os valores de acidez titulável inicial das formulações A, B e C foram 0,15%, 0,16% e 0,14%, respectivamente. No final do processo, a acidez atingiu os valores 0,93%, 0,98% e 0,86%, respectivamente. As contagens de S. thermophilus das formulações A, B e C não apresentaram diferença significativa nos tempos de 1, 14 e 28 dias e as contagens médias foram, respectivamente, 9,04, 9,20 e 8,77 log UFC/g. Desta forma, a utilização de FPBV e inulina não influenciou no processo de produção de leite fermentado inoculado com Streptococcus thermophilus e na multiplicação do micro-organismo durante o armazenamento do produto.
Were the Ethiopians in Jerusalem Ottoman Citizens? Ethiopian Essentialism versus Ottomanism (1850–1916)
Authors: Ancel Stéphane
Published: December 2020

Between 1850 and 1903 Europeans and Ottomans were in conflict regarding the status of Ethiopians living in Jerusalem. According to the Ottomans, Ethiopians in Jerusalem were Ottoman subjects. European powers like Great Britain, France, and Italy contested this opinion. According to them, Ethiopians in Jerusalem were not subjects of the Ottoman Empire but of the Ethiopian kingdom and as such they held an Ethiopian identity, not an Ottoman one. We will see that the first issue at stake here was the European protection of Ethiopians in Jerusalem. But we will show that the discourse proposed by Ethiopians to their interlocutors in Jerusalem concerning what is supposed to be the Ethiopian identity played an important role. In order to reach their goals in Jerusalem, Ethiopians played the game of Europeans while avoiding directly confronting Ottoman authorities. But in supporting the point of view of the Europeans, Ethiopians developed Ethiopian essentialism, solely centered on the Christian characteristics of Ethiopian identity. Between 1904 and 1916, this essentialism came into conflict with the new social reality of the Ethiopian kingdom.

Studies that demonstrate the effects of sources of nitrogen (N) applied before or after irrigation on the yield of winter crops are limited in literature. In this sense, the objective of this study was to compare the effect of sources of N applied immediately before or after 13 mm irrigation of wheat and bean winter crops. It was used a randomized complete block design, with 4 replicates, in a 5 × 2 + 1 factorial scheme, and 11 treatments consisted of five N sources: urea, polymer-coated urea, urea + ammonium sulfate, ammonium sulfate, and ammonium nitrate and a control treatment (without N fertilization). For wheat, although ammonium nitrate provided great N content in the leaves, the grain yield was lower due to the lodging of the plants; since the application of N either before or after irrigation did not influence the grain yield. Regarding the bean, N fertilization increased productivity, but there were no differences among N sources and, despite the greater N content in the leaves observed with the N supply before irrigation the greatest grain yield was observed when N was applied after the irrigation.

Published: December 2020

Pseudomonas syringae pv. actinidiae is a bacterial pathogen of kiwifruit. Based on the results of the pathogenicity assay, we sequenced the strain Pseudomonas syringae (Psa3) P155 which possesses a series of virulence and resistance genes, CRISPR candidate elements, prophage related sequences, methylation modiﬁcations, genomic islands as well as one plasmid. Most importantly, the copper resistance genes copA, copB, copC, copD, and copZ as well as aminoglycoside resistance gene ksgA were identified in strain P155, which would pose a threat to kiwifruit production. The complete sequence we reported here will provide valuable information for a better understanding of the genetic structure and pathogenic characteristics of the genome of P155.

Published: December 2020

Brazil is currently the world’s largest producer and exporter of sugarcane, and the crop has high socioeconomic importance in the country. Root-knot nematodes (Meloidogyne spp.) are one of the major limiting factors in sugarcane production. These plant parasites have wide geographic distribution, high damage potential, and are difficult to control. Recently, the species Meloidogyne enterolobii was identified in sugarcane crops in the state of Pernambuco, Brazil. Given the importance of genetic resistance for integrated nematode management and the lack of research on the M. enterolobii–sugarcane pathosystem, this study aimed to assess the response of sugarcane cultivars to M. enterolobii. Thirteen cultivars were evaluated for their resistance to M. enterolobii based on the nematode reproduction factor. The experiment was conducted in a greenhouse, in a completely randomized design, with 14 replicates. Pre-sprouted sugarcane seedlings were transplanted to 5 L pots, and each pot was considered an experimental unit. At 15 days after transplanting, the seedlings were inoculated with 5,000 eggs and second-stage juveniles of M. enterolobii. Tomato and okra plants were also inoculated to test the viability of the inoculum. At 240 days after inoculation, plant roots were processed and evaluated for nematode number. This parameter was used to calculate the nematode reproduction factor on each cultivar. All sugarcane cultivars were found to be immune to M. enterolobii, with a reproduction factor of 0.

The boron (B) fertilization in soybean is important to ensure great yields. Boron correction must be applied in deficient soils repairing losses, exports and leaching. The objective of this study was to evaluate the effects of doses, methods and times of application of B in soybean B content and yield. The field experiments were conducted during the 2015/16 and 2016/17 cropping seasons and set as a randomized block design with nine treatments (0, 0.5, 1, 1.5, 2 kg ha-1 of B, 0.5 kg ha-1 of B mixed with NPK (02-28-18) in furrow during sowing, foliar application with 0.3 kg ha-1 of B in V4 soybean stage, foliar application with 0.3 kg ha-1 of B in R1 soybean stage, and foliar application of 0.15 kg ha-1 in V4 plus 0.15 kg ha-1 of B in R1 soybean stage) and four replications. Boric acid was the B source and the variables analyzed were: B leaf content, B exported in seeds, number of pods per plant, number of seeds per pod, weight of 100 seeds (g) and productivity (kg ha-1). The levels of B in leaf were between 30.1 and 43.8 mg kg-1 and between 65.0 and 92.6 mg kg-1 in the 2015/16 and 2016/17 growing season, respectively. Exports of B in seeds were estimated between 166 and 248 g ha-1 and between 208.9 to 260.8 g ha-1 in the 2015/16 and 2016/17 growing season, respectively. Great productivity (3,820 kg ha-1) was observed in the 2016/17 growing season, with an estimated dose of 0.95 kg ha-1 of B.

The selection of potato plants (Solanum tuberosum L.) that are efficient in the use of phosphorus (P) plays an important role in increasing crop productivity, reducing the cost of production due to the high price of phosphate fertilizers, as well as reducing the pollution of the environment due to the better use of the applied fertilizers. The objective of this work was to compare the method of selection of potato clones for the efficiency of use and response to P between in vitro and off - soil systems with the use of sand as substrate. To that end, potato clones SMIC 148-A, Dakota Rose, SMINIA 793101-3, SMIB 106-7, SMIF 212-3, SMIJ 319-1 and P 150 were cultivated at low and high levels of P in the culture systems in vitro (1,935 and 19,346 mg P L-1) and off-soil (2.32 and 23.2 mg P L-1). The selection of potato clones using only as a criterion the accumulation of P under low nutrient level is not adequate, both in off-soil and in vitro cultivation. Clones selected as being more efficient in the use of P in in vitro cultivation do not prove to be necessarily more efficient in off-soil cultivation. No clone remains in the same classification group regarding the efficiency of use and response to P, based on the production of dry mass, in the two cropping systems.

Effects of different soil tillage and sowing systems (Conventional Soil Tillage – CST: Moldboard plough + gobble disc + disk harrow + harrow + sowing machine; Reduced Soil Tillage – RST: rototiller-combined soil tillage machine + sowing machine; Ridge Sowing – RS: gobble disc + ridge-sowing machine; Direct Sowing – DS – no-till) on plant development and emergence traits of second-crop soybean were investigated in this study under Antalya provincial conditions. Experiments were conducted over the experimental fields of Aksu Branch of Bati Akdeniz Agricultural Research Institute for 3 years (2013, 2014, 2015) as a fixed experiment. The number of days to 50% emergence, number of days to 50% flowering, plant height, number of pods per plant, the first pod height, number of plants per m2, 1000-seed weight and yield were considered as plant development parameters. Mean emergence time, germination rate index, emergence ratio, space ratio, tillering ratio and acceptable plant spacing ratio were considered as plant emergence parameters. Different soil tillage and sowing systems generally had significant effects on investigated traits at p<0.01 and p<0.05 levels.

This study will reveal the quality of the textbooks used in DIY for high school students. From this research, the textbook standard will become a reference so that it can be used to achieve the goals of regional language education that have been mandated in the curriculum. This is a descriptive study. The data were collected from the WIBAWA book "Wiyata Basa Jawa". The research instrument consisted of WIBAWA textbook assessment instrument with Fry Graph instruments/indicators. WIBAWA textbook readability was 66.67%, while 33.33% of the book did not meet legibility. The 33.33% unacceptability does not mean completely unacceptable, but there are parts that are too easy and some parts that are too difficult, so it needs to be revised.

Authors: Fatmawati Andriyana , Insani Nur Hanifah
Published: December 2020

Suluk Tenun reflects the image of Javanese women based on the background of Islamic religious traditions. Judging from the cultural feminism approach, this research uses descriptive qualitative methods and modern philology, which aims to describe the image of Javanese women listed in the text of Suluk Tenun. The data source used in this research is the text Suluk Tenun, a collection of Pura Pakualaman Library, located at pupuh VII Serat Piwulang Estri, and consists of 17 verses. The results showed that the text of Suluk Tenun was loaded with Javanese moral and cultural values. The symbols for the tools and the weaving process are used to describe the image of Javanese women in controlling their passions when they are married, such as telanjuk, kaki, kuping, kisi, and others. In the Suluk Tenun text, several images must have by a woman to be able to become a holy woman. The images are women who must be knowledgeable, able to control their passions, and able to rely on faith in God and the shari'a.

Transthoracic echocardiography is the first-line imaging modality in the assessment of right-sided valve disease. The principle objectives of the echocardiographic study are to determine the aetiology, mechanism and severity of valvular dysfunction, as well as consequences on right heart remodelling and estimations of pulmonary artery pressure. Echocardiographic data must be integrated with symptoms, to inform optimal timing and technique of interventions. The most common tricuspid valve abnormality is regurgitation secondary to annular dilatation in the context of atrial fibrillation or left-sided heart disease. Significant pulmonary valve disease is most commonly seen in congenital heart abnormalities. The aetiology and mechanism of tricuspid and pulmonary valve disease can usually be identified by 2D assessment of leaflet morphology and motion. Colour flow and spectral Doppler are required for assessment of severity, which must integrate data from multiple imaging planes and modalities. Transoesophageal echo is used when transthoracic data is incomplete, although the anterior position of the right heart means that transthoracic imaging is often superior. Three-dimensional echocardiography is a pivotal tool for accurate quantification of right ventricular volumes and regurgitant lesion severity, anatomical characterisation of valve morphology and remodelling pattern, and procedural guidance for catheter-based interventions. Exercise echocardiography may be used to elucidate symptom status and demonstrate functional reserve. Cardiac magnetic resonance and CT should be considered for complimentary data including right ventricular volume quantification, and precise cardiac and extracardiac anatomy. This British Society of Echocardiography guideline aims to give practical advice on the standardised acquisition and interpretation of echocardiographic data relating to the pulmonary and tricuspid valves.
The gut microbiome, endocannabinoids and metabolic disorders
Authors: Iannotti Fabio Arturo , Di Marzo Vincenzo
Published: December 2020

Two complex systems are emerging as being deeply involved in the control of energy metabolism. The intestinal microbiota, with its warehouse of genes, proteins and small molecules, that is, the gut microbiome; and the endocannabinoid system, with its recent extension to a more complex signalling apparatus including more than 100 lipid mediators and 50 proteins, that is, the endocannabinoidome. Both systems can become perturbed following bad dietary habits and during obesity, thus contributing to exacerbating this latter condition and its consequences in both peripheral organs and the brain. Here, we discuss some of the multifaceted aspects of the regulation and dysregulation of the gut microbiome and endocannabinoidome in energy metabolism and metabolic disorders, with special emphasis on the emerging functional interactions between the two systems. The potential exploitation of this new knowledge for the development of new pharmacological and nutritional approaches against obesity and its consequences is also briefly touched upon.
Territorio y materialidad en el Bajo Segura durante el Bronce Final inicial: nuevos datos del asentamiento de Cobatillas la Vieja (Santomera, Murcia)

Published: December 2020

El Sureste de la Península Ibérica experimentó durante el Bronce Final significativos procesos de reordenación poblacional visibles en la configuración espacial de sus asentamientos y en el nuevo paisaje político-territorial de la región. En el caso de la vega baja del Segura, el abandono de parte de los asentamientos postargáricos propició una orientación del poblamiento hacia nuevas posiciones en altura, bien interconectadas y estrechamente ligadas con las capacidades productivas de sus entornos. Paradigma de tales procesos es el asentamiento de Cobatillas la Vieja, inserto en un paisaje de amplia biodiversidad y relaciones territoriales arraigadas en épocas previas que facilitaron su reocupación en el nuevo escenario sociopolítico y económico de la zona. El análisis de tales circunstancias desde el prisma de la arqueología del paisaje, en conjunción con el estudio de la territorialidad e identidad de su materialidad, constituye el objetivo de este trabajo. Como resultado se pone de manifiesto la importancia de este enclave y su contextualización con el resto de centros cercanos con el fin de delimitar las problemáticas particulares que se dieron en las primeras etapas del Bronce Final en el Bajo Segura.
La ceca de Nakur
Authors: Canto García Alberto J.
Published: December 2020

Durante el siglo X, la presencia del poder político e influencia de los omeyas en el Magreb se hace patente, no solo en los grandes envíos de monedas acunadas en Córdoba para financiar la guerra con los fatimíes y sus aliados y la compra de voluntades sino, también, en las emisiones de moneda a nombre de los omeyas en algunas ciudades del Magreb. A las dos más importantes de F?s y Nak?r se han ido anadiendo, en anos recientes, otras cecas que baten moneda a nombre de los omeyas. Sin duda la más importante de todas ellas fue la de F?s, con una producción bastante intensa mientras que la de Nak?r, en contra de lo sugerido en alguna ocasión, parece tener una producción mucho más limitada. El objetivo del presente trabajo es realizar una recopilación y revisión de sus series analizando, por vez primera, un detallado repertorio de las imágenes y de la documentación historiográfica sobre la que se elaboraron los primeros repertorios de esta ceca, con el propósito de establecer con claridad los tipos, modelos y fechas conocidas de esta ceca para realizar una aproximación más acertada de su importancia o del volumen potencia de sus acuñaciones.
