Published: August 2020

Background: Regular physical activity during pregnancy is known to have positive effects on the health of the mother and fetus. However, reports indicate that more than half of pregnant women in Iran do not have adequate physical activity. This study was conducted in order to change the behavior of pregnant women in regard to physical activity and also to develop suitable educational/interventional measures. Objectives: This study was conducted to investigate the effects of health belief-based education on the physical activity of nulliparous women. Methods: This triple blinded randomized control trial was conducted among 64 nulliparous women attending the health centers of Ilam, Iran, in 2018. Participants were selected randomly by the cluster sampling method and were allocated to the two groups of control and intervention. Participants in the intervention groups received education and theoretical training based on the health belief model for at least 45 minutes, and then individual practical training was provided. Samples in the control group received routine pregnancy training. Data were collected in two pre-test and post-test stages by a valid questionnaire and were analyzed by SPSS, version 19, using statistical tests, including Chi-square, paired t-test, and independent t-test. Results: The results showed that the levels of perceived sensitivity (-4.750 ± 2.119), (t = 12.215, P ≤ 0.001), perceived severity of threat (-5.312 ± 1.874), (t = -16.036, P < 0.001), perceived benefits (-2.750 ± 1.502), (P < 0.001, t = -10.352), and self-efficacy (-3.656 ± 1.405), (P < 0.001, t = -14.708) in the intervention group significantly increased after the training compared to pre-training. Also, the level of perceived barriers (4.093 ± 1.444), (P < 0.001, t = 16.027) after the training was significantly less than pre-training level. In the intervention group, the total physical activity with the intensity of moderate/severe (2049/000 ± 963.342), (P < 0.001, t = -12.032) was significantly higher than pre-training. Conclusions: The results of this study indicated that training based on the health belief model can increase the physical activity of pregnant women with moderate/severe intensity and bring it to the optimal level of 150 minutes per week by increasing the health beliefs of pregnant women. Therefore, it is suggested that training based on this model should be appropriately incorporated into the routine education of pregnant women.
Sociedad del miedo y desafección constitucional
Authors: Sánchez Barrilao Juan Francisco
Published: August 2020

En este trabajo el autor trata de mostrar la relación entre el miedo y la desafección constitucional. Primero, analiza el paso de la sociedad del riesgo a una sociedad del miedo, y concreta en el riesgo tecnológico, la globalización, la radicalización de identidades y en el rol de Internet. Luego advierte cómo la democracia se está enfrentando ante una política comprometida por el miedo, a la aparición de nuevos conflictos y a las respuestas iliberales que ya se dan. También el autor plantea cómo afrontar constitucionalmente el miedo respecto a la seguridad, al patriotismo constitucional, además de a otras formas de contención y promoción. Por último, el autor insiste en las causas del miedo como motor de la desafección constitucional.
Seguridad Social y principio de solidaridad
Authors: Alonso Seco José María
Published: August 2020

En este artículo, después de describir la noción de solidaridad, su origen histórico y rasgos que la caracterizan, se analiza cómo dicho principio ha venido a constituir uno de los fundamentos básicos de los sistemas de Seguridad Social, en su modalidad contributiva y no contributiva. Se examina su incorporación al ordenamiento jurídico español de Seguridad Social: en la Constitución y en la legislación ordinaria. Del análisis realizado se desprende que la solidaridad ha sido un principio que el Tribunal Constitucional y la legislación han consolidado progresivamente como pieza angular de la Seguridad Social, de manera que esta ya no puede entenderse sin referencia directa a la solidaridad interpersonal, interterritorial e intergeneracional Se concluye el artículo con tres reflexiones que afectan al principio de solidaridad: necesidad de reforzarlo en las prestaciones contributivas y no contributivas, mantenimiento del sistema de reparto y mantenimiento del régimen económico de la Seguridad Social como competencia exclusiva del Estado.

La modificación del artículo 168 de la Constitución Española a través del procedimiento ordinario de reforma
Authors: Álvarez Suárez Juan
Published: August 2020

La escasa activación del poder de reforma en el ordenamiento constitucional español ha sido justificada por parte de la doctrina, entre otros motivos, por la excesiva rigidez y complejidad de nuestros procedimientos de reforma, y más específicamente el consagrado en el art. 168 CE. En este trabajo reflexionamos sobre la modificación de este precepto, habida cuenta de la existencia de un debate clásico acerca del procedimiento más adecuado para acometer dicha labor. Más específicamente, planteamos la posibilidad de que, en determinadas ocasiones, su reforma se lleve a cabo a través de la técnica procedimental prevista en el art. 167 CE. Nuestra propuesta, basada en una interpretación literal del precepto combinada con una interpretación teleológica nos permite, de un lado, preservar el respeto hacia el tenor literal de la norma y, de otro, tener presente la finalidad con la que esta fue incorporada en nuestra Constitución.
Algunas propuestas graduales de democratización del procedimiento de reforma constitucional
Authors: González Cadenas Diego
Published: August 2020

En los últimos años, una parte de la doctrina constitucional española ha centrado su atención en el procedimiento de reforma constitucional de la Constitución española de 1978 planteando diversas propuestas de reforma. La práctica totalidad de los investigadores que han dedicado esfuerzos a la cuestión lo han hecho partiendo de una concepción de Constitución de acuerdo con la cual el proceso por el cual se conforma es considerado secundario, cuando no irrelevante, o restando importancia a la posibilidad de participación ciudadana directa. El objeto de este artículo es plantear una serie de propuestas graduales de democratización del procedimiento de reforma constitucional desde un enfoque diferenciado del de la mayoría de la doctrina. Por un lado, se asume que una Constitución no se caracteriza únicamente por ser un conjunto de normas fundamentales que encabezan un ordenamiento jurídico, sino que es un texto que, para ser tal, requiere de un procedimiento democrático y participativo en el que pueda hacerse efectiva la máxima según la cual una Constitución es un acuerdo de la sociedad sobre cómo debe regirse y gobernarse el Estado. Por otro lado, la metodología de análisis que se emplea, prácticamente inexplorada por la doctrina española, parte de los análisis del campo de estudio comúnmente conocido como constitution-making. Derivado de ello, los resultados a los que se llega difieren sustancialmente de lo planteado hasta el momento.
Constitución y bloque constitucional
Authors: Pulido-Ortiz Fabio Enrique
Published: August 2020

Las constituciones contemporáneas suelen incluir cláusulas de remisión que otorgan relevancia constitucional a normas que no son formuladas por el texto constitucional. Para explicar el funcionamiento de estas cláusulas, la jurisprudencia y la dogmática han desarrollado la doctrina del bloque constitucional. No obstante, esta doctrina emplea el término «bloque constitucional» en dos sentidos distintos. Por un lado, el término se emplea para referirse a las normas que no son formuladas en el texto de la constitución pero que tienen jerarquía constitucional. Por otro lado, se usa para referirse a normas que, aun cuando no tienen jerarquía constitucional, son aplicadas para resolver asuntos constitucionales. El objetivo de este artículo es analizar estos sentidos de bloque constitucional y precisar las relaciones y diferencias conceptuales que existen entre ellos. La conclusión del trabajo es que -en el contexto de una constitución rígida- la integración del bloque constitucional (en el sentido de normas con jerarquía constitucional) depende de que las cláusulas de remisión constituyan (o se refieran a) mecanismos de reforma constitucional. De lo contrario, si las cláusulas de remisión no constituyen (o si no se refieren a) mecanismos de reforma constitucional, entonces el bloque constitucional solo puede constituirse por un conjunto de normas aplicables pero que no son parte de la constitución (i.e que no tienen jerarquía constitucional).
Subsidiariedad y reparación sobreviniente: Una propuesta alternativa para el sistema interamericano de derechos humanos
Authors: Candia Falcón Gonzalo , Reyes Arellano Francisca
Published: August 2020

Existen ocasiones en las cuales los Estados reparan el daño producido a víctimas de violaciones de derechos humanos durante la tramitación del caso respectivo ante la Comisión o la Corte Interamericana de Derechos Humanos. En esa situación, ambas instituciones suelen continuar el proceso hasta su término. Este trabajo propone cambiar esta aproximación. En efecto, los autores sugieren que, en aquellas circunstancias, tanto la Comisión como la Corte concluyan la tramitación de esos casos. Ello porque, de acuerdo con las exigencias del principio de subsidiariedad, la intervención de los órganos regionales del sistema de protección solo se justifica en la medida que los Estados no reparen adecuadamente a las víctimas.
Asphalt Layer Density and Air Voids Content: GPR and Laboratory Testing Data Reliance
Authors: Baltrušaitis Andrius , Vaitkus Audrius , Smirnovs Juris
Published: August 2020

The assurance of asphalt pavement layer compaction, expressed by ratio between field and laboratory bulk density and air voids content, is one of the main criteria of the durability of asphalt road pavement. Destructive measures should be applied and cores should be taken from the asphalt pavement seeking to determine the representative compaction level of the constructed asphalt layers. New methods are constantly being sought for fast, non-destructive and accurate asphalt layer density and air void determination on road. Ground Penetrating Radar (GPR) can allow determining the qualitative characteristics of asphalt pavement across the entire length of the road without causing damage to the road structure. Relative dielectric permittivity, usually called dielectric value or constant, is the leading property used in GPR applications on road pavement surveys. This article presents GPR measurement results from asphalt base and binder layers of four test sections. GPR measurements were conducted immediately after the end of asphalt layer compaction process. Test points on each layer were selected and density, air void content were determined by drilling cores and testing them in the laboratory. To estimate asphalt layer density and air void content, GPR data were analysed using different existing mathematical models. To justify the reliability of the data measured by GPR, results were checked by comparing them with the results measured directly on cores taken from the asphalt pavement layers.
Assessment of Skid Resistance of Road Pavements
Authors: Šneideraitienė Lina , Žilionienė Daiva
Published: August 2020

The quality of the paved road depends not only on the decisions of the road designer and the work carried out but also on the materials used. Most of the aggregates used are imported from other countries. However, the usage of domestic materials reduces the cost of the road pavement and the use of aggregates produced by a special production technology in Lithuania, i.e., dolomite aggregates instead of granite aggregates. Experimental studies were carried out on the skid resistance of the road surface. It was found that the coefficient of skid resistance met the requirements for surface dressing with dolomite aggregate, and the results were analysed with 95% probability. This coefficient partially met the requirements for asphalt concrete, while it did not meet the requirements at all for stone mastic asphalt. The surface roughness, however, met the requirements for road sections where granite aggregates were used instead of dolomite in mixes of surface dressing and asphalt concrete. The analysis was carried out considering the volume of traffic and the service life of the individual road sections. It was determined that it was suitable for a 5-year guarantee period to perform the surface dressing, wearing course of asphalt concrete and stone mastic asphalt with dolomite aggregate where part of heavy vehicles is less than 20% of traffic flow. The use of granite aggregates was justified only in the road where heavy vehicles dominated.

Temporal inference from laboratory testing results and triangulation with clinical outcomes extracted from unstructured electronic health record (EHR) provider notes is integral to advancing precision medicine. Here, we studied 246 SARS-CoV-2 PCR-positive (COVIDpos) patients and propensity-matched 2460 SARS-CoV-2 PCR-negative (COVIDneg) patients subjected to around 700,000 lab tests cumulatively across 194 assays. Compared to COVIDneg patients at the time of diagnostic testing, COVIDpos patients tended to have higher plasma fibrinogen levels and lower platelet counts. However, as the infection evolves, COVIDpos patients distinctively show declining fibrinogen, increasing platelet counts, and lower white blood cell counts. Augmented curation of EHRs suggests that only a minority of COVIDpos patients develop thromboembolism, and rarely, disseminated intravascular coagulopathy (DIC), with patients generally not displaying platelet reductions typical of consumptive coagulopathies. These temporal trends provide fine-grained resolution into COVID-19 associated coagulopathy (CAC) and set the stage for personalizing thromboprophylaxis.
The Sec1/Munc18 protein Vps45 holds the Qa-SNARE Tlg2 in an open conformation

Published: August 2020

Fusion of intracellular trafficking vesicles is mediated by the assembly of SNARE proteins into membrane-bridging complexes. SNARE-mediated membrane fusion requires Sec1/Munc18-family (SM) proteins, SNARE chaperones that can function as templates to catalyze SNARE complex assembly. Paradoxically, the SM protein Munc18-1 traps the Qa-SNARE protein syntaxin-1 in an autoinhibited closed conformation. Here we present the structure of a second SM–Qa-SNARE complex, Vps45–Tlg2. Strikingly, Vps45 holds Tlg2 in an open conformation, with its SNARE motif disengaged from its Habc domain and its linker region unfolded. The domain 3a helical hairpin of Vps45 is unfurled, exposing the presumptive R-SNARE binding site to allow template complex formation. Although Tlg2 has a pronounced tendency to form homo-tetramers, Vps45 can rescue Tlg2 tetramers into stoichiometric Vps45–Tlg2 complexes. Our findings demonstrate that SM proteins can engage Qa-SNAREs using at least two different modes, one in which the SNARE is closed and one in which it is open.
Termite inspired algorithm for traffic engineering in hybrid software defined networks
Authors: Ammal R Ananthalakshmi , PC Sajimon , SS Vinodchandra
Published: August 2020

In the era of Internet of Things and 5G networks, handling real time network traffic with the required Quality of Services and optimal utilization of network resources is a challenging task. Traffic Engineering provides mechanisms to guide network traffic to improve utilization of network resources and meet requirements of the network Quality of Service (QoS). Traditional networks use IP based and Multi-Protocol Label Switching (MPLS) based Traffic Engineering mechanisms. Software Defined Networking (SDN) have characteristics useful for solving traffic scheduling and management. Currently the traditional networks are not going to be replaced fully by SDN enabled resources and hence traffic engineering solutions for Hybrid IP/SDN setups have to be explored. In this paper we propose a new Termite Inspired Optimization algorithm for dynamic path allocation and better utilization of network links using hybrid SDN setup. The proposed bioinspired algorithm based on Termite behaviour implemented in the SDN Controller supports elastic bandwidth demands from applications, by avoiding congestion, handling traffic priority and link availability. Testing in both simulated and physical test bed demonstrate the performance of the algorithm with the support of SDN. In cases of link failures, the algorithm in the SDN Controller performs failure recovery gracefully. The algorithm also performs very well in congestion avoidance. The SDN based algorithm can be implemented in the existing traditional WAN as a hybrid setup and is a less complex, better alternative to the traditional MPLS Traffic Engineering setup.
Modular automatic design of collective behaviors for robots endowed with local communication capabilities
Authors: Hasselmann Ken , Birattari Mauro
Published: August 2020

We investigate the automatic design of communication in swarm robotics through two studies. We first introduceGiandujaan automatic design method that generates collective behaviors for robot swarms in which individuals can locally exchange a message whose semantics is not a priori fixed. It is the automatic design process that, on a per-mission basis, defines the conditions under which the message is sent and the effect that it has on the receiving peers. Then, we extendGiandujatoGianduja2andGianduja3, which target robots that can exchange multiple distinct messages. Also in this case, the semantics of the messages is automatically defined on a per-mission basis by the design process.Giandujaand its variants are based onChocolate, which does not provide any support for local communication. In the article, we compareGiandujaand its variants with a standard neuro-evolutionary approach. We consider a total of six different swarm robotics missions. We present results based on simulation and tests performed with 20 e-puck robots. Results show that, typically,Giandujaand its variants are able to associate a meaningful semantics to messages.
CMTM6 significantly relates to PD-L1 and predicts the prognosis of gastric cancer patients
Authors: Li Xin , Chen Ling , Gu Chuan , Sun Qiaoli , Li Jia
Published: August 2020

Background

The CKLF-like MARVEL transmembrane domain containing 6 (CMTM6) is a key regulator of the programed death receptor ligand-1 (PD-L1) protein. However, the usefulness of CMTM6 expression as a prognostic indicator and the relationship between CMTM6 and PD-L1 expression in gastric cancer (GC) remains unclear.

Objectives

We evaluated the expression and prognostic implications of CMTM6 in GC tissue and its relationship with PD-L1 expression.

Patients and methods

The protein expressions of CMTM6 and PD-L1 were detected in 122 cases of postoperative GC tissue using immunohistochemical (IHC) assays. Kaplan–Meier survival analysis was used to calculate the survival probability and a log-rank test was used to compare the survival curves. Univariate and multivariate Cox proportional hazard regression analyses were used to evaluate the clinically-related factors associated with survival. Pearson’s correlation was used to determine the correlation analysis and estimate the statistical significance. The univariate and multivariate logistic regression analyses were used to analyze the relationship between clinically-related factors and PD-L1 expression.

Results

Kaplan–Meier survival analysis showed that patients with high CMTM6 expression had shorter overall survival (OS) than those with low expression (P < 0.001). The expression of CMTM6 was an independent risk factor for prognosis in multivariate Cox proportional hazard regression analyses (HR:2.221, CI% [1.36–3.628], P = 0.001). The OS of patients with positively expressed PD-L1 was significantly shorter than those with negatively expressed PD-L1 (P = 0.003). The expression of CMTM6 was significantly related to the positive expression of PD-L1 in gastric cancer tissues (r = 0.186, P = 0.041). The expression of CMTM6 was the independent risk factor for PD-L1 expression in multivariate logistic regression analysis (OR:2.538, CI% [1.128–5.714], P = 0.024).

Conclusion

CMTM6 expression is significantly related to PD-L1 and may be a useful prognostic indicator and a specific therapeutic target for cancer immunotherapy for GC patients.

Published: August 2020

Background

Pink bollworm (Pectinophora gossypiella) is a destructive insect pest of cotton crops in China and globally, which is actively predated on by Orius strigicollis. Studies on the fitness or survival of O. strigicollis fed on P. gossypiella at different temperatures have not been reported. The fitness of O. strigicollis may be well explained using two-sex life table parameters. Thus, the present study provides important insights for the effective biocontrol of P. gossypiella.

Methodology

Considering the importance of fitness parameters and biocontrol, the present study explores the feeding potential and age-stage, two-sex life table traits of O. strigicollis on P. gossypiella eggs at different temperatures (24, 28 and 32 °C) in the laboratory.

Results

The intrinsic rate of increase (r) was higher at 28 °C (0.14 d−1) than at 24 °C (0.0052 d−1) and 32 °C (0.12 d−1). Similarly, the net reproductive rate (R0) was higher at 28 °C (17.63 offspring) than at 24 °C (1.13 offspring) and 32 °C (10.23 offspring). This concluded that the maximum feeding potential and growth capacity of O. strigicollis could be attained at 28 °C when fed on P. gossypiella eggs. O. strigicollis adults preferred to feed on P. gossypiella eggs compared with first instar larvae. Based on these results, the present study suggests that O. strigicollis represents a promising biological control agent against P. gossypiella eggs in cotton fields.

Bundelkhand region of Uttar Pradesh (UP), India is a major pulse producer in the Indian subcontinent. The agriculture production, particularly, pulses have been playing a great role in strengthening the economic conditions and are the source of livelihood of Bundelkhand region of Uttar Pradesh state. The productivity of chickpea crop is low due to lack of adoption of best management practices of chickpea by farmers Keeping these constraints under consideration the yield gap and technology gap assessed of the region by conducting Cluster Front Line Demonstrations on best management practices of chickpea during Rabi seasons in the year 2015-16 to 2018-2019, respectively. The demonstration was carried out in six villages of Mahoba district. The results revealed that the full technological gap in 5 practices (variety, seed treatment, seed inculcation with Rhizobium, weed management practices and plant protection), a partial gap in 3 practices (seed rate, fertilizer management and irrigation) and Nil gap in 2 practices (land preparation and sowing methods). Further, Average grain yield of chickpea showed a remarkable increase (32%) in CFLDs compared to Farmers practice (check). However, it is still behind to potential yield. The average technological gap, extension gap and technology index were 8.10 q ha-1, 3.30q ha-1 and 36.6% respectively. The study recommends the improvement of productivity of chickpea may be achieved through fulfilling the gap between demonstration yield and farmers practice yield. Therefore, more effort requires to determine the socio-economic factors for practicing age-old practice and extension efforts needed to the rapid diffusion of best management practices. Further, The future study on variable climate conditions and edaphic factors requires to determine the gap between potential and demonstration yield.

Thousand grain weight of the variety is 22.8 g and it has colored grain tip. The rice has zinc content 27.6 mg/kg, 25.9% amylose content with 9.7% protein content. BRRI dhan84 was released as a high yielding, zinc enriched rice variety to meet  the nutritional (zinc) demand of the country. The zinc enriched BRRI dhan84 is a superb variety for cultivating in the dry (Boro) season and farmers can be economically benefited and the country will be nutritionally benefited by the cultivation of BRRI dhan84.
Effect of Salinity Stress on Antioxidative Enzyme Activity in the Leaves of Tolerant and Susceptible Genotypes of Groundnut
Authors: Pal Apurba , Dutta Debjani , Pal Anjan Kumar , Gunri Sunil Kumar
Published: August 2020

Aims: To better understand the physiological and biochemical mechanisms in the light of antioxidative enzymes activity under salinity stress between tolerant and susceptible genotypes of groundnut.

Study Design: Completely Randomized Design.

Place and Duration of Study: The laboratory experiment was carried out in the departmental laboratory of Plant Physiology, Bidhan Chandra Krishi Viswavidyalaya (BCKV), Mohanpur, Nadia, and West Bengal during the year 2017-18.

Methodology: A controlled study was conducted to screen 26 genotypes of groundnut under 200 mM NaCl salinity stress. Fourteen-day old seedlings were subjected to salinity treatment. For this, the modified Hoagland nutrient solution containing 200 mM NaCl (osmotic potential: -0.8 MPa) was applied in each case and the pH was adjusted to 6.3. The treatments were repeated on every third day. Control set without salinity stress was also maintained similarly in each case for comparison of results.

Results: The salt tolerance index or STI of the genotypes ranged from 47.57% to 96.40%. Out of all the genotypes KDG-197 (STI= 96.40%) was found to be the most tolerant under a salinity stress of 200 mM NaCl and it was closely followed by R 2001-2 (STI=87.92%), VG 315 (STI=84.05%), TCGS 1157 (STI=77.59%) and TG 51 (STI=73.67%). While the genotypes Girnar 3 (STI= 47.57%), OG 52-1 (STI=49.09%), TVG 0856 (STI= 49.28%) and J 86 (STI= 50.66%) were the most susceptible genotypes based on their relative performance under stress in respect of total dry weight. It has been noted further that, out of the nine genotypes, enhancement of antioxidative enzyme like super oxide dismutase (SOD), guaiacol peroxidase (GPOX) and catalase (CAT) activity was recorded maximally in tolerant genotype KDG 197 (64.18%, 71.74% and 52.82% increase over control respectively) and R 2001-2 (53.68 %, 93.48% and 53.96 % increase over control respectively) but the activity of these enzyme in the four susceptible genotypes declined considerably under salinity treatment.

Conclusion: Tolerant genotypes of groundnut in general registered much higher activities of antioxidative enzymes in their leaves as compared to the susceptible genotype under high salinity stress.

Study Design: The complete randomized block design (CRBD) with 4 repetitions was implemented.

Place and Duration of Study: The experimental site is located at Allada, in southern Benin, and conducted between May 2017 and July 2017.

Methodology: During this study, two factors were tested (Tillage and mulch) and 6 treatments have been obtained of combination of two factors level (No-tillage, tillage and 0%, 50%, 75% mulch). The growth parameters, yield parameters and harvest index were determined.

Results: The results indicated that tillage and mulching significantly influenced the growth rate, leaf surface and leaf number of maize plants. Tillage increased to 54% the grain yield compared to no tillage whereas 50% and 75% mulch promoted the highest grain yield. Considering the combination of tillage and mulching, LM50 (Tillage + 50% mulch) and LM75 (Tillage + 75% mulch) treatments resulted in about 85% increase of grain yield compared to direct seeding without mulch.

Conclusion: These results reflect the importance of soil cover in improving of maize productivity.

The importance of sourcing products of natural origin in boosting immunity against infectious diseases during therapeutic interventions especially in developing countries has been underscored. The need therefore arose to investigate candidate sources within locally available flora based on identified ethno-practices in the region. The potentiality of Aframomum melegueta as a source of vitamins which are recognized immune boosters was investigated. Plant samples were collected from the wild near Akungba-Akoko, Ondo state, Nigeria and separated into Stem, Leaf sheath, Fruit pulp (mesocarp) and Seed parts. The samples were oven-dried, pulverized and extracted with methanol and filtered with Whatman No 1 filtered paper. The filtrates were concentrated in-vacuo using vacuum rotary evaporator at 40°C and was later concentrated to dryness in a ventilated oven at 40°C. Analyses of vitamin content of the samples were conducted using standard analytical methods. The plant displayed a rich array of Vitamins with the seeds having the highest concentration compared to the Stem, Leaf sheath, Fruit pulp (mesocarp) and Seed extracts. Values obtained for seed and stem extracts respectively were Vitamin C (16.8 mg/g, 5.85 mg/g), Vitamin B (1.15 mg/g, 0.41 mg/g), Vitamin B3 (0.98 mg/g, 0.30 mg/g), Vitamin E (0.75 mg/g, 0.11 mg/g), Vitamin B6 (0.03 mg/g, 0.006 mg/g), Vitamin B12 (4.22 mg/g, 0.50 mg/g), Vitamin A (1024.1 mg/g, 189.9 mg/g), Vitamin E (0.75 mg/g, 0.11 mg/g), Vitamin D (0.68 mg/g, 0.03 mg/g) and Vitamin K (0.017 mg/g,0.007 mg/g). Standard daily recommended intakes for each vitamin are vitamin C -75 mg, B2, 3, 6 and B12 ranges from 2 mg to 18 mg, A -600 µg, E -10 mg, D -5 µg, and vitamin K -80 µg.  This study therefore elucidates the richness of Aframomum melegueta in essential vitamins and suggests its potential as an immune booster especially during the outbreaks of diseases. Direct consumption of the plant parts studied or as food supplement formula will be of benefit in the management of diseases.

Authors: Elmalky Fatma M. , Ismail M. N. , Mohamedien Ghada F.
Published: August 2020

In the present work, the equations of motion of the solar sail are derived in the restricted three–body system. The dimensionless coordinates are used to obtain the solution of the problem. The Laplace transformations are used to solve these systems of equations to obtain the components of the solar sail acceleration. The motion about L2, L4 and its stability are studied under obalteness effects. The results obtained are in good agreement with previous results in this field. It is remarked that this model has special importance in space-dynamics to enabling spacecraft to do some maneuvers depends on the solar sail acceleration.
Examining Developed versus Emerging Economy Online Food and Beverage Purchase Behaviour and Predictors: A Survey Comparison of Indian, Chinese, Indonesian, Japanese and United Kingdom Consumers
Authors: Driver Timothy , Tait Peter , Saunders Caroline , Dalziel Paul , Guenther Meike , Rutherford Paul
Published: August 2020

Aims: Consumers are increasingly using online shopping for purchasing food and beverage (F&B) products. A challenge to industry stakeholders is understanding which elements of online digital media and smart technologies are associated with higher rates of online expenditure that could be strategically targeted. Therefore, the central aims of this study are to identify predictors of online F&B expenditure, and how they differ across developed and emerging economy consumers.

Study Design: This is a quantitative study based on cross-sectional survey data.

Place and Duration of Study: The study is based on data collected in India, China, Indonesia, Japan and the United Kingdom in April 2016.

Methodology: Primary data is collected using online surveys of consumers primarily responsible for F&B grocery shopping within the household. Questionnaires focused on eliciting online expenditure rates for F&B, and associated use of relevant online digital media and smart technologies. Fractional multinomial logit modelling is used to identify statistically significant determinants of respondents’ percentage of expenditure online in each country.

Results: The sample consists of 5,004 respondents: China (1,001), India (998), Indonesia (1,002), Japan (1,002), UK (1,001). In-market technology use is a stronger predictor of online F&B expenditure in emerging than in developed economy markets. The influence of digital information sourcing behaviour and demographics are weak predictors of online F&B expenditure across both developed and emerging economy markets. In general, consumers in emerging economies show greater engagement with digital media and smart technology in relation to online F&B expenditure than their developed economy counterparts.

Conclusion: There is significant variation across countries in the specific determinants of online food and beverage expenditure and the uptake of associated digital media and smart technologies. These insights provide useful direction for focusing effort in targeting channel activators specific to each markets characteristics.

Authors: Melchiotti Gonçalves Amanda , Guerra Dhyovana , Deitos Roberto Antonio
Published: August 2020

A proposta do artigo é analisar a qualidade na educação a partir da definição de competência proposta pelo Banco Mundial no documento “Competências e Empregos: Uma Agenda para a Juventude”, de 2018. Parte-se do pressuposto de que as competências descritas pelo Banco Mundial (2018), representam o status quo da cultura liberal-conservadora do século XXI. Por conta disso, o artigo retoma o contexto de referência das políticas educacionais, com o intuito de compreender o movimento histórico, político e econômico das políticas educacionais. Corrobora-se com o fato de que a educação, sob a perspectiva expressa pelo Banco Mundial (2018), está imersa na viabilidade imediata, na busca de capital humano.

Não se trata aqui de empreender um julgamento de valor a respeito das ideias de Saffioti, tampouco tomar como dogmas suas concepções. O intento da análise é compreender como suas contribuições podem ser tomadas como referência na discussão sobre a educação numa perspectiva feminista, sobretudo, considerando a histórica luta de classes.
A lógica-categorial da desigualdade nos Manuscritos marxianos de 1844
Authors: Peto Lucas Carvalho
Published: August 2020

O objetivo desse artigo é expor a lógica-categorial da desigualdade de classes nos Manuscritos marxianos de 1844. A desigualdade no regime do capital para si, em uma exposição que se baseia na lógica-categorial marxiana, se fundamenta na propriedade privada dos meios de produção e na exploração da força de trabalho da classe trabalhadora. O artigo expõe a lógica desse processo a partir de uma análise da constituição do capital enquanto modo de sociabilização para si.

Para tal, tratamos das aproximações e distanciamentos das concepções desenvolvidas pelas autoras Silvia Federici e Roswitha Scholz, na medida em que em suas obras recentes trataram deste importante tema para pensarmos hoje a questão de gênero em relação à formação, desenvolvimento e crise do modo de produção capitalista.

 
Aportes para a compreensão da opressão da mulher no capitalismo
Authors: Marinho Siqueira Sandra Maria , Marinho Pereira Victor Bruno
Published: August 2020

O presente artigo tem por finalidade oferecer aportes para a compreensão da opressão da mulher no capitalismo, a partir do referencial marxista. Para tanto, nos baseamos, fundamentalmente, nas contribuições de Engels (2012), Lessa (2012), Leacock (2012), Saffioti (2013) e Davis (2016), buscando reconstruir a análise materialista da origem da opressão e apontar elementos específicos da sua manifestação na sociabilidade capitalista. Este texto, portanto, sinaliza uma perspectiva crítico-transformadora das relações de opressão de gênero, insuperáveis nos marcos do trabalho alienado e do regime do grande capital.

Fundadora da Organização Revolucionária Marxista - Política Operária (ORM-Polop), exilou-se no Chile no período da ditadura militar brasileira, participando ativamente da luta de classes travada na América Latina. Com a abertura do regime democrático, retornou ao Brasil e contribuiu com a fundação do PDT,  do qual rompeu em 2000.
Gênero e marxismo: contribuições para a história das ciências
Authors: Santana Carolina Queiroz , Andrade Ingrid Silva de , Santos Victor Ferreira Dias
Published: August 2020

Neste ensaio teórico, questionamos: Qual a contribuição da teoria marxista e do feminismo marxista para a história das mulheres nas ciências? Para isso, revisamos os estudos de feminismo/marxismo e/ou gênero/marxismo, e propomos quatro teses para a história das mulheres nas ciências:   1. O Materialismo Histórico - Dialético refuta argumentos de superioridade masculina na ciência por mero essencialismo biológico; 2.A análise do feminismo marxista à categoria de gênero proporciona uma crítica a ciência pautada em determinações absolutas; 3. O feminismo Marxista defende o espaço privado como esfera política; 4. A história social, sob um viés marxista, se configura como instrumento importante para a escrita de história das mulheres nas ciências.
