ABSTRACT

The digital multimedia environment where research communication develops nowadays has important consequences for EAP course design (Pérez-Llantada 2016), since speaking and visuals are ever more decisive for communicative success (Crawford-Camiciottoli and Fortanet-Gómez 2015). However, intonation manuals have remained virtually unchanged for decades, reflecting a time of limited access to actual academic intonation in use. To countervail this situation, we draw on Hafner’s (2018) multimodal analysis of experimental biology Video Methods Articles by examining the intonation used in an exploratory corpus of the Researcher’s Introduction section, identified as the most hybrid in generic nature. Our analysis suggests that traditional Hallidayan intonation explained in handbooks like Hewings (2007) and Brazil (1994) fails to capture phenomena observed in our corpus. These intonational phenomena (mostly deviations from traditional tonicity) have been found to be consistent with genre-specific factors like communicative purpose and move structure. Consequently, a broader revision of academic intonation materials is proposed.

ABSTRACT

In “Spanish for the Professions and Specific Purposes: Curricular Mainstay,” Doyle discusses how SPSP is poised to become an “adaptable signature feature of future Spanish curricula” (2018: 96). For SPSP to become a mainstay, Doyle argues that it requires “greater needs-grounded imagination (…) whose potential SPSP portfolios will vary according to educational missions and contexts” and proposes certificate programs as responsive and adaptable programs to fit diverse curricular contexts (96-97). In this paper, the authors discuss the development of a cross-disciplinary certificate program in Bilingual Professional Writing (Spanish/English) at a public university on the U.S./Mexico border to meet the needs of our unique student body and to better prepare students as globally-minded writing professionals. This model values students’ home languages and echoes Collier and Thomas’ (2004) assertion that a bilingual and dual language approach can be astoundingly effective at the university level.
Protección del patrimonio arquitectónico y arqueológico en la Córdoba de la posguerra. La Comisión Provincial de Monumentos y el templo romano de la calle Claudio Marcelo
Authors: BUGELLA ALTAMIRANO MATILDE
Published: July 2020

En 1951 comienza en Córdoba la excavación de un edificio de culto altoimperial, primer elemento descubierto de un ambicioso complejo arquitectónico destinado a monumentalizar la entrada a la ciudad desde la Via Augusta. Su exhumación guarda una estrecha relación con los procesos de renovación urbanística acometidos durante unos los años del desarrollismo, en los que se diseñó el modelo de ciudad al servicio del tráfico rodado, en buena medida aún vigente. El hallazgo del templo vino a recordar a la ciudad, junto al valor de su pasado romano, la necesidad de preservar su patrimonio arquitectónico y la trama urbana histórica.
COMPARATIVE STUDY OF LASER METAL DEPOSITION (LMD) OF COAXIAL WIRE AND POWDER IN THE MANUFACTURE OF TI-6AL-4V STRUCTURES

Published: July 2020

The aeronautical sector has begun to bet on additive manufacturing as an alternative for the manufacture of titanium components. In this sense, the Laser Metal Deposition (LMD) is presented as a direct deposition technology of great potential, mainly for the manufacture of large structural components. The deposition of material in powder form is the most used method, however, the heads of coaxial deposition of wire developed in the last years allow, a priori, to manufacture structures with a better efficiency and feeding rate. In this work a comparative study is carried out between the processes of laser deposited coaxial wire and powder in order to verify the highest deposition rates and efficiencies of the wire feed. For this purpose, several walls have been deposited with the highest deposition rate achieved in a parametric search for both wire and powder format and the difference between the material fed and the material deposited has been calculated. The two formats have also been analysed in terms of microstructural and geometric quality. It is observed that wire exceeds powder in terms of deposition rates and efficiency. However, geometric limitations and more unfavourable microstructural structures can be seen.

Keywords: LMD, Ti-6Al-4V, additive manufacturing, wire, powder, coaxial.

The additive manufacturing industry has developed significantly, which includes metal printing techniques; with a wide range of applications, great projections and future expectations. Technologies such as SLM or LMD have gone from being considered as a rapid prototyping process to consolidating in a primary manufacturing process
Despite the great advances made in metal printing, there are still aspects of quality, dimensional and finish that require the need for subsequent actions to metallic printing (thermal treatments, subtractive manufacturing) for the scope of structural integrity and dimensions definitive
This paper presents a methodology based on the robust design approach, which allows to integrate the main hybrid process with 4 support processes for the control of performance metrics and the mitigation of the effects of noise factors through the strategic use of the controllable factors under a predictive, preventive and technical approach.
A case study is presented where the phase of the vibration control applied to a type of elbowed ducts is analyzed, which allows to obtain an adequate tendency of the type and location of fixation system that leads to improve the quality of the finishing.

Keywords: SLM, machining, geometric distortion, dimensional control, heat treatment, robust design
LASER WELDING DEPTH EVALUATION BY MEANS OF AN ANALYTIC MODEL
Authors: ARRIZUBIETA ARRATE JON IÑAKI , HERNANDO ARRIANDIAGA IÑIGO , LAMIKIZ MENTXAKA AITZOL , UKAR ARRIEN ENEKO
Published: July 2020

An analytical model has been developed for the laser welding process which, based on multipole theory, predicts the depth of the weld bead at a very low computational cost. For this, the model starts from the thermal field previously calculated considering only the heat transfer by conduction, and includes the influence of the monopoles, dipoles and quadrupoles, which allows considering the finite thickness of the sheet to be welded, the latent heat of the material and the internal movement of the molten material, respectively.
The model has been experimentally validated for Inconel 718 and the case in which a wobble strategy is used, which is a combination of linear advance motion and superposed oscillatory motion resulting in a trochoidal trajectory. For the different situations analyzed, and thanks to the consideration of multipole, the model is able to determine the depth of the weld bead with an error below 12%. This is a considerable improvement over the situation in which the multipole effect was not considered and the heat transfer was modelled only by conduction, since in this case around 50% errors are obtained, which demonstrates the validity of the model.

Keywords: Laser welding, wobble, analytical model, multipole theory.
ON THE ANALYSIS OF COMPUTER VISION AND ULTRASOUND BASED TECHNIQUES FOR THE IN-SERVICE INSPECTION OF AERONAUTICS PARTS PRODUCED BY ADDITIVE LAYER MANUFACTURING (ALM)

Published: July 2020

Bionic Aircraft is a project founded under the framework H2020 and it is a result of a need to reduce emissions due to the impact of the growth of the aviation industry. The introduction of Additive Layer Manufacturing (ALM) to produce some metal aircraft parts is considered as an opportunity to address this issue. This technology allows to produce ultra-lightweight and highly complex parts (so-called "bionic parts").
One of the actions to consider in the project is the development of new Non-Destructive Technologies (NDT) strategies to inspect, in-service, parts produced by ALM made of Al-based alloys. This need arises because, ALM processes for these alloys are at low maturity level (Technology Readiness Level - TRL1) and hence, no proven and certified NDT methods are yet developed. Moreover, in-service inspection of aeronautic bionic parts involves challenges like the uncertainty of the inner inspection of a layered material, the lack of accessibility (the part is attached to the aircraft fuselage), and the unexpected defects under in-service conditions, something still under study.
The objective of this work is to assess the inspection, in-service, of this kind of parts, by selecting and customizing the most suitable NDT methods, according to the type and maximum tolerable damage sizes estimated by a fatigue life prediction evaluation.

Keywords: computer vision; ultrasound; additive manufacturing; cracks and defects detection

Published: July 2020

The purpose of this paper is to study and outline the effects of infill parameters (percentage and pattern) using fused deposition manufacturing on mechanical properties of PLA printed samples.
Three infill patterns were tested (rectilinear, honeycomb and Hilbert curve) while infill percentage was tested at three levels (20, 60 and 90 per cent). The properties examined were tensile strength, tensile modulus, elongation, Charpy impact test, morphology of the fractures of tensile and impact test and thermo mechanical analysis. Also, a thermal analysis was done using differential scanning calorimetry to the raw polymer in order to determine the processing temperature.
Results showed the influence of the filling parameters in 3D printing on the mechanical properties of the obtained part. The filling pattern greatly influences the mechanical properties of parts with low filling percentages. Honeycomb filling pattern is the one with better mechanical results.
The complexity of the filling pattern influences on the processing time. Nozzle direction changes in complex patterns lengthen processing time.
Results can significantly influence custom design and manufacturing of parts using material fused deposition modeling.

Jean-Luc Marion y Kant. ¿Es trascendental el argumento de Anselmo?
Authors: Neumann Soto Hardy Alberto
Published: July 2020

En este artículo se sostiene que, según Marion, el argumento anselmiano tiene rasgos trascendentales. Esta lectura busca apoyar su tesis interpretativa según la cual el llamado argumento ontológico no es propiamente uno tal. Si esa suposición es correcta, se hace necesario determinar cuál es el sentido de lo trascendental con que opera Marion y hasta dónde se despliega tal carácter en su lectura. Cualquiera sea el caso, el asunto afecta la condición ontológica o no ontológica, según se decida, del argumento de Anselmo.
La legitimación iusnaturalista del derecho positivo en I. Kant
Authors: Cubo Ugarte Óscar
Published: July 2020

En el presente trabajo vamos a presentar tres modos distintos de abordar el derecho positivo con vistas a ilustrar la legitimación kantiana del estado civil por medio del abandono del estado de naturaleza. El primero de ellos remite a la Teoría pura del derecho de Hans Kelsen y a su positivismo jurídico puramente descriptivo. El segundo modo que vamos a considerar es el positivismo ético o normativo de J. Waldron y su defensa prescriptiva del derecho positivo. Por último, y fundamentalmente a partir de los trabajos de J. Waldron sobre el positivismo jurídico de Kant extraeremos las razones de fondo de la defensa iusnaturalista del derecho positivo presente en la “Doctrina del derecho” de la Metafísica de las Costumbres.

Authors: Gutiérrez-Braojos Calixto , Montejo Gámez Jesús , Poza Vílches Fátima , Marín-Jiménez Ana
Published: July 2020

La Construcción de Conocimiento (CC) es un marco teórico que promueve la indagación colectiva para resolver problemas del conocimiento relevantes en una comunidad educativa. Hay un número cada vez mayor de autores que buscan los beneficios de este enfoque, por lo que se necesita una visión general de las tendencias de la investigación. El objetivo de este estudio es proporcionar el estado del arte relacionado con la producción de investigación sobre la pedagogía de la Construcción de Conocimiento, incluidas las tendencias y temas relevantes. En este estudio se aplicó un diseño explicativo secuencial que combina los enfoques cuantitativos (análisis cienciométrico) y cualitativos (revisión sistemática). La muestra se seleccionó de las producciones más recientes publicadas en revistas indexadas en la base de datos Web of Science. El análisis cienciométrico muestra una dinámica de publicación típica de un campo de investigación emergente. En la fase cualitativa, el análisis revela las tendencias de investigación sobre la creación de conocimiento, así como los beneficios de ponerlo en práctica en una amplia gama de contextos, exponiendo que la tecnología es un componente relevante del aprendizaje basado en la pedagogía. Estos beneficios se refieren principalmente a la profundidad de pensamiento de los individuos y las habilidades de colaboración dentro de entornos de aprendizaje sostenidos por computadora.
Participación e implicación del estudiante en la evaluación: implicar a todo el estudiante en la búsqueda de la justicia y el bien social
Authors: McArthur Jan
Published: July 2020

En este artículo ofrezco una perspectiva sobre la participación de los estudiantes en la evaluación informada por la teoría crítica y sustentada por un compromiso con una mayor justicia social dentro y a través de la educación superior. Se basa en trabajos anteriores sobre la evaluación de la justicia social para argumentar que la participación de los estudiantes en la evaluación debe ser considerada más ampliamente, no solo que los estudiantes realicen determinadas tareas. En lugar de ello, debemos pensar en el estudiante como una persona completa, socialmente situada y en las formas en que la participación en las tareas de evaluación fomenta tanto el bienestar individual como el social. Hay tres corrientes en el argumento propuesto. En primer lugar, la investigación sobre la evaluación debe hacer más para problematizar la naturaleza del conocimiento y que la comprensión de las complejidades del conocimiento en la educación superior tiene vínculos tanto con las experiencias de nuestro estudiante como una persona completa, como con justicia social. En segundo lugar, los propósitos de la evaluación deberían orientarse hacia la noción de teoría crítica de un bien común, en la que el bienestar individual y social están dialécticamente interrelacionados. Por último, al pensar en la participación del estudiante en la evaluación. debemos ir más allá de la fusión del mundo real con el mundo del trabajo, que figura en gran parte de la literatura sobre la evaluación auténtica. Propongo, en cambio, la importancia de entender el ámbito económico como una esfera amplia y heterogénea que no puede desarticularse del ámbito social.
¿Herederas de una degeneración atávica o víctimas de la miseria? Género y racismo en el discurso médico sobre la prostitución en Cuba, 1902-1913
Authors: Garrido Torres Catalina del Mar
Published: July 2020

Objective/Context: We will analyze the medical discourse on prostitution in Cuba, paying special attention to how a diagnosis of this phenomenon was constructed, which oscillated between racial and social explanations, sustained by gender distinctions and racism that survived the ravages caused by the wars of independence in the Cuban postcolonial context of the early twentieth century. Originality: In the article, we suggest that gender and “race” were categories of identity that did not refer to pre-existing or self-evident realities, but that, in the case of Cuba, emerged as sociocultural and discursive constructions that responded to the pressures of a new political order, forged between the last war for independence (1895-1898), the two military interventions by the United States on the Island (1898-1902 and 1906-1909) and the first years of republican life. Methodology: From an analysis of studies conducted by Cuban Physicians Dr. Ramón M. Alfonso and Dr. Matías Duque, key figures in the system that regulated prostitution between 1902 and 1914, we note the way in which historic, racial and social arguments were threaded together to express the anxieties surrounding prostitution (the women who practiced it and the world around them), in a society that privileged the mother, the wife, the daughter, and the white woman as a national prototype. Conclusions: We show that gender functioned as a historically situated form of differentiation thaht categorized prostitutes in relation to their distance from certain racially defined ideals of femininity and masculinity. Likewise, the racial and social explanations of prostitution were not self-excluding, in the same way that rejecting the “other”, their racial and gender differences, was not contradictory with its inclusion, albeit at the margins, in a nation that ideally would have to be white and heteronormative.
La construcción de modelos femeninos de Victoria Ocampo entre 1920 y 1940: reconsideraciones sobre Margherita Sarfatti y Virginia Woolf
Authors: Streppone Maria Victoria
Published: July 2020

Objective/Context: This article analyzes gender as a conceptual category that served as the basis for the work of the Argentinian magazine Sur, directed by Victoria Ocampo. The objective is to rebuild the ideals of its protagonist from specific figures who were vital in the construction of modern, feminine models. Methodology: The research analyzes archived documents and an extensive bibliography that allows understanding the ideals that guided the specific processes that would serve as the basis for Victoria Ocampo’s literary strategies. Originality: This work shows that gender can be expressed in multiple registers, as a function of feminine presences that acquire the condition of models. Conclusions: The article proposes an extraliterary interpretation of selected feminine presences around whom the issue of gender is problematized, which is conceived here as a critical sensibility that induces devising certain strategies whereby functional models are selected and proposed for the construction of a local feminine identity.

Published: July 2020

Habitat directly affects the population size and geographical distribution of wildlife species, including the Mangshan pit viper (Protobothrops mangshanensis), a critically endangered snake species endemic to China. We searched for Mangshan pit viper using randomly arranged transects in their area of distribution and assessed their habitat association using plots, with the goals of gaining a better understanding of the habitat features associated with P. mangshanensis detection and determining if the association with these features varies across season. We conducted transect surveys, found 48 individual snakes, and measured 11 habitat variables seasonally in used and random plots in Hunan Mangshan National Nature Reserve over a period of 5 years (2012–2016). The important habitat variables for predicting Mangshan pit viper detection were fallen log density, shrub density, leaf litter cover, herb cover and distance to water. In spring, summer and autumn, Mangshan pit viper detection was always positively associated with fallen log density. In summer, Mangshan pit viper detection was related to such habitats with high canopy cover, high shrub density and high herb cover. In autumn, snakes generally occurred in habitats near water in areas with high fallen log density and tall shrubs height. Our study is the first to demonstrate the relationship between Mangshan pit viper detection and specific habitat components. Mangshan pit viper detection was associated with habitat features such as with a relatively high fallen log density and shrub density, moderately high leaf litter cover, sites near stream, and with lower herb cover. The pattern of the relationship between snakes and habitats was not consistent across the seasons. Identifying the habitat features associated with Mangshan pit viper detection can better inform the forestry department on managing natural reserves to meet the habitat requirements for this critically endangered snake species.

Published: July 2020

The present study provides baseline information on the quantitative and qualitative estimation of aeromycoflora. Burkard personal airsampler and Anderson two stage airsampler were used to detect the quantitative and qualitative estimation of aeromycoflora. 17 non-viable fungal spores were recorded with the aid of Burkard personal airsampler and 12 viable fungal genera were detected using Anderson two stage airsampler. Higher concentration airborne fungi observed in the month of March. Aspergillus sp, Ascospore, Basidiospore, Curvularia sp, Alternaria sp were found to be Nigrospora sp most predominant nonviable fungal genera whereas dominant viable genera were Aspergillus sp, Penicillium sp, Cladosporium sp, Curvularia sp, Trichoderma sp and  Fusarium sp in both the environments. The result of antifungal potential of Clerodendrum infortunatum showed highest efficacy against Aspergillus sp followed by Penicillium sp and Fusarium sp. This present study provided the baseline information about the viable and non-viable concentration in the study sites. Besides the outcomes of this study along with the insightful explanation could aptly provide basis for strategizing effective preventive measures against airborne-fungi. Those are responsible for causing different agricultural crops diseases and human respiratory ailments.

Insecticidal Property of Black Seed (Nigella sativa) Powder as an Eco-friendly Management of Skin Beetle Dermestes maculatus (Coleoptera: Dermestidae) in Atlantic Codfish Gadus morhua (Gadiformes: Gadidae)
Authors: Bekinwari Bob-Manuel, R. , Boate Ukoroije, R.
Published: July 2020

The bio-pesticidal potential of Nigella sativa seed powder in the management of Dermestes maculatus in codfish (Gadus morhua) was evaluated in the laboratory. D. maculatus beetles were obtained from naturally infested smoked fish, cultured at ambient temperature for the establishment of new stock and same age adults. Purchased N. sativa seeds were ground into fine powder, weighed at 0.4 g, 0.8 g, 1.2 g, 1.6 g and 2.0 g for use in the bioassay. The treatments were separately added into 40 g codfish kept in Kilner jar into which two sexed pairs of D. maculatus were introduced and observed. From the results, the number of the developmental stages (larvae, pupae and adults) of D. maculatus in codfish treated with N. sativa seed powder was inversely proportional to the concentration of the seed powder. Thus, an increase in the concentration of N. sativa powder generated reduction in the mean number of D. maculatus progeny found in the codfish after 35 days as follows: at 0.4 g, progeny development was (103.50, 7.75, 2.50) and 77.00, 8.25 and 1.00 at 2.0 g respectively for larva, pupa and adult stages. Percentage protection conferred by the botanical on D. maculatus showed that all the doses applied were effective. Corrected mortality of D. maculatus adults after 45 days of exposure to the different doses of N. sativa treatments also increased with an increase in concentration of N. sativa from 0.4 g to 2.0 g. Frass weight generated by D. maculatus activity in codfish treated with N. sativa powder was high in codfish treated at 1.6 g. Finally, N. sativa characterized both qualitatively and quantitatively for phytochemicals, proved the secondary metabolites with bio-pesticide potentials against D. maculatus such as phenols, Alkaloid, flavonoid, terpenoid, saponin, tannin, Cardiac glycoside, anthraquinone, steroid and oxalate in different proportion, therefore, should be utilized in Integrated Pest Management program of stored codfish.
Purposes of Using Informal Social Learning Spaces by Students: A Case Study of Business School in Sri Lanka
Authors: Amarathunge B. , Madhuwanthi L. A. Pavithra
Published: July 2020

Business Schools are more than mere collections of classrooms and offices, rather destinations for studying, collaboration, group discussions, and they contribute to developing a sense of community among students and faculty. The literature illustrates almost zero essences on how managerial decision-making about space concerns affect students or faculty. In fact, it is been noted o reflect their understanding of the purpose of physical spaces mostly in its outward form which then interpreted by observers following their socially constructed decoding. The main objective of this study is to examine for what purposes students are using informal  Social Learning Spaces. This is a qualitative case study based on a Business School in Sri Lanka. The data were gathered through focus group interviews and observations held at three  different purpose-built informal social learning spaces at the selected Business School and analyzed using the thematic framework. In this exploration, the thoughts, feelings, emotions, and judgments of students are brought into the discussion. The findings revealed that students use social learning spaces for their studying, leisure, and networking purposes. Therefore, by providing informal social learning spaces for students to engage themselves in educational activities can make an influence on higher learning outcomes in academic, personal, and social aspects of their life.

Aim: To evaluate the interleukin 3 levels in some Hepatitis B virus and Human immunodeficiency virus (HIV) positive subjects.

Study Design: Cross sectional study.

Place and Duration of Study: Haematology Department, University of Nigeria Teaching Hospital Enugu, Nigeria, between June and September, 2019.

Methodology: A total of 86 subjects were recruited for this study; 40 were positive for the human immunodeficiency virus, 30 were Hepatitis B positive and 16 healthy subjects that served as controls. The controls had tested negative to Hepatitis B Virus, Human immunodeficiency Virus and hepatitis C virus infections. Whole blood samples were collected from the Human immunodeficiency Virus positive and control samples. Haemoglobin concentration was analysed using the Orphěe Mythic 22 automated analyzer. Serum samples collected from all 86 subjects were used to assay Interleukin 3 using the Enzyme Linked Immunosorbent assay based Finetest human interleukin 3 kit.

Results: A highly significant decrease in interleukin 3 levels was observed in Hepatitis B Virus and Human immunodeficiency virus positive subjects when compared with the apparently healthy control subjects, (P = 0.000 < 0.05). Average hemoglobin levels were also lower in the Human immunodeficiency virus subjects compared with the controls.

Conclusion: A reduction of the interleukin 3 may be part of the synergistic factors responsible for the anaemia usually seen in the viral infections.

In today’s competitive world, packaging and edible coating play a significant part in producing usefulness user affable products for marketing. Due to several drawbacks of conventional packaging materials (wooden boxes, gunny bags, pallet, pallet bins, Wire-Bound Crates etc.) new technologies of polymeric films (LDPE, HDPE, Shrink film, Cling film) are adopted. By use of polymeric film (non perforated) modified atmosphere is obtain within the package, which subsequently helps to enhance shelf life of fruits. Application of thin layers of edible coating onto fruit surface helps to modify inner environment of fruit which causes similar effect to the modified atmospheric storage. This technological strategies are helpful to retard water loss, reduces skin damage caused by friction, changes in gaseous composition, moisture content, volatile aromas, and transport of solutes from the fruits overly enhance cosmetic appearance, decreasing ripening process and rise shelf life of fruits.

Authors: Uket N. O. Sam- , Bate G. B.
Published: July 2020

Aims: This study was aimed at determining the concentration of heavy metals (Pb, Cd, Fe and Au) in mango plant parts (roots, stem barks, leaves and fruits) from two gold mining areas (Maraba and Duke) and the control (Kadauri) in Zamfara State, Nigeria for establishment of a baseline data for these metals and determining the suitability of the mango fruit for consumption.

Study Design: Analytical study design was applied in a stratified manner for the research.

Place and Duration of Study: The study was carried out in the environmental technology laboratory, National Research Institute for Chemical Technology (NARICT), Zaria, Nigeria between March and August 2019.

Methodology: A cumulative total of 96 samples of plant parts (roots, stem barks, leaves and fruits) were collected and analysed for Lead, Cadmium, Iron and Gold using Atomic Absorption Spectrophotometer (AAS) after digestion with a mixture of 20 ml HNO3 and 8 ml HClO4.

Results: The results obtained for the mean metal concentrations were; most abundant, Pb (62.07 ± 54.09 mg/kg) in mango roots from Duke and the least abundant, Cd (0.52 ± 0.44 mg/kg) in fruits from Kadauri. All the metals had very high (> 0.5) translocation factors indicating fast movement from the roots to the shoots while the mean values of these metals in the fruits were found to be above the WHO and FAO maximum permissible limits which shows high level of contamination as a result of gold mining activities. Metals generally occurred in the order: Pb>Fe> Au > Cd and they differed across sampling stations with the mining areas having significantly (P<0.05) higher values than the control.

Conclusion: Heavy metals concentration in mango plant was found to be generally higher than the permissible limits hence the fruits are considered unsuitable for human consumption.

Maize genotypes of different maturity groups with good seed quality had been developed, but there is little or no information on how the seed quality of the maize genotypes are affected by their maturity groups. Therefore, the objectives of this study were to evaluate maize varieties of different maturity groups for seed quality and determine genotypic variations that exist within the different maturity groups of maize for seed quality. Laboratory experiments were conducted in the Seed Science Laboratory of the Department of Crop Production and Protection, Obafemi Awolowo University, Ile-Ife, Nigeria. Seeds of sixteen maize genotypes of different maturity groups were subjected to imbibition, germination, accelerated ageing, conductivity and seedling vigor tests. The late maturity group (TZLCOMP.4DTF2,TZLCOMP. 1C6/DT.SYN-1-W, WHITEDTSTR/TZLCOMP.1-W, OBASUPER1) gave the best viability, speed of germination and days to complete germination while the extra early maturity group (2009TZEE-ORISTRQPM, 2000SYNEE-WSTR,2013TZEE-WDTSTR, TZEE-WPOPDTC2STRC5F2) had the least performance. The early (2014TZE –YDTSTR, 2013DTESTR–WSYN, EVDT-2000STRC0, 2009DTEWSTRSYN) and extra-early maturity groups had the longest root length and highest root number respectively. However, the different maturity groups of maize evaluated imbibed water at the same rate. TZEE-WPOP DT STR C5 F2, 2013 DTE STR – W SYN, AFLATOXIN R-SYN2, TZL COMP.1 C6/DT. SYN-1-W among extra early, early, intermediate and late maturity groups respectively performed best for viability and vigor tests.

Objective

We have conducted a study to clarify the association between amphetamine‐related disorders (ARD) and the risk of developing dementia.

Methods

This study used a retrospective cohort design by using Taiwan’s National Health Research Institute Database. A random sample of 68,300 subjects between January 1, 2000, and December 31, 2015, was obtained, comprising of 17,075 patients with ARD, and 51,225 controls without ARD (1:3), matched for gender and age group. After adjusting for covariates, a Fine and Gray’s survival analysis (competing with mortality) was used to compare the risk of dementia during a 15‐year follow‐up period.

Results

In the present study, 1,751 of 17,075 patients with ARD and 2,147 of 51,225 in the control group without ARD (883.10 vs 342.83 per 100,000 person‐years) developed dementia. ARD cohort was more likely to develop dementia (hazard ratio = 4.936 [95% CI: 4.609–5.285, P < 0.001). After adjusting for gender, age groups, education, monthly insured premiums, urbanization level, geographic region, comorbidities, the hazard ratio for ARD patients was 5.034 (95% CI: 4.701–5.391, P < 0.001). ARD has been associated with overall dementia, Alzheimer dementia, vascular dementia, and other dementia. Both the amphetamine use disorder and amphetamine‐induced psychotic disorders were associated with the risk of overall dementia, Alzheimer dementia, vascular dementia, and other dementia.

Interpretation

This study shows that patients with ARD, both the amphetamine use disorder and the amphetamine‐induced psychotic disorder, may have a nearly fivefold risk of developing dementia, including Alzheimer dementia and other types of dementia.

Lead‐halide perovskite quantum dots (PQDs) or more broadly, nanocrystals possess advantageous features for solution‐processed photovoltaic devices. The nanocrystal surface ligands play a crucial role in the transport of photogenerated carriers and ultimately affect the overall performance of PQD solar cells. Significantly improved CsPbI3 PQD synthetic yield and solar‐cell performance through surface ligand management are demonstrated. The treatment of a secondary amine, di‐n‐propylamine (DPA), provides a mild and efficient approach to control the surface ligand density of PQDs, which has an apparently different working mechanism compared to previously reported surface treatments. Using an optimal DPA concentration, the treatment can simultaneously remove both long‐chain insulating surface ligands of oleic acid and oleylamine, even for unpurified PQDs with high ligand density. As a result, the electrical coupling between PQDs is enhanced, leading to improved charge transport, reduced carrier recombination, and a high power conversion efficiency approaching 15% for CsPbI3‐PQD‐based solar cells. In addition, the production yield of CsPbI3 PQDs can be increased by a factor of 8. These results highlight the importance of developing new ligand‐management strategies, specifically for emerging PQDs to achieve scalable and high‐performance perovskite‐based optoelectronic devices.

Published: July 2020

Effective delivery of therapeutic agents into brain tissue for therapy of glioma remains a big challenge due to the presence of the blood‐brain barrier (BBB). Herein, a disulfide bond on–off–on triplet regulation strategy is developed to endow transferrin nanoparticles with high up to 18.1% drug‐loading efficiency. Such transferrin nanoparticles of around 70 nm, specifically, DOX@Tfm NPs, are synthesized via self‐assembly of modified transferrin with hydrophobic doxorubicin (DOX), displaying glutathione (GSH)‐responsive DOX release behavior in the tumor microenvironment. These DOX@Tfm NPs maintain the naturally targeted activity of transferrin, which can effectively cross the BBB and target the transferrin receptor overexpressed on the surface of glioma cells for precise chemotherapy of orthotopic glioma. In vivo results confirm that DOX@Tfm NPs can effectively target orthotopic glioma in living mice, achieving enhanced efficiency in inhibiting tumor growth and increasing survival rate without obvious side effects being observed. This study presents a new avenue to develop natural protein materials as promising smart drug delivery systems for clinical transformation.

Prognosis for castration‐resistant prostate cancer (CRPC) is poor, and no effective therapeutic regimen is yet known. The PI3K/Akt/mTOR pathway plays a predominant role and may be a promising molecular target for CRPC. However, the toxicity of the dual PI3K inhibitors in clinical trials limits their clinical efficacy for CRPC. To solve this problem, a highly integrated precision nanomedicine strategy is employed to molecularly and physically target CRPC through enhanced targeted drug delivery efficiency and reduced unwanted side‐effects. Gedatolisib (Ge), a potent inhibitor of PI3K/mTOR, is formulated into disulfide cross‐linked micelle platform (NanoGe), which exhibits excellent water solubility, small size, excellent stability with redox stimulus‐responsive disintegration, and preferential uptake at tumor sites. NanoGe improves the anti‐neoplastic effect of free Ge by 53 times in PC‐3M cells and 13 times in C4‐2B cells, through its enhanced uptake via caveolae‐ and clathrin‐mediated endocytic pathways and the subsequent inhibition of the PI3K/mTOR pathway, resulting in Bax/Bcl‐2‐dependent apoptosis. In vivo, NanoGe shows superior efficacy than free Ge, and synergizes with nanoformulated cabazitaxel (NanoCa) as a nanococktail format to achieve a cure rate of 83%. Taken together, the results of this study demonstrate the potency of NanoGe in combination with NanoCa against CRPC.
