Acacia mangium Willd est une espèce à croissance rapide, fixatrice d’azote, capable de restituer au sol des éléments minéraux par chute de litière. Elle est actuellement très utilisée dans les programmes de reboisement. L’effet substrat sur la biomasse des plants, à l’âge de plantation, a été estimé dans le but d’optimiser les conditions de production des plants. Un dispositif en blocs complets randomisés comprenant six types de substrats à base de terre noire, charbon et sciure de bois, a été mis en place. Des jeunes plants âgés de trois semaines ont été transplantés dans des plaques alvéolées comprenant différents substrats puis élevés jusqu’à l’âge de plantation. Une dose de 30 g d’engrais NPK dilués dans 10 l d’eau a été apportée quotidiennement aux plants. Les résultats obtenus montrent un effet substrat sur la biomasse et la croissance. Les plants issus des substrats 6 (75% terre+25% charbon) et 4 (50% terre+50% charbon) présentent les meilleures performances de croissance. L’Activité Réductrice d’Acétylène (ARA) réalisée a été influencée par le substrat. La dose de fertilisation apportée n’a pas engendré l’avortement des nodules. Le substrat 5 (50% de terre noire, 25% de charbon et 25% de sciure de bois) offre les conditions optimales de développement des nodules.Mots clés : Substrat, Acacia mangium, biomasse, ARA.

English Title: Effect of substrate on the biomass and the symbiotic fixing of nitrogen by Acacia mangium willd. (Fabaceae) seedlings in the nurseryAcacia mangium Willd is a rapid growth species, fixing of nitrogen and able to restore on the ground biogenic salts through the fall of litter. It’s currently very used in the afforestation programs. The effect of substrate on the seedlings biomass at the plantation age was estimated with the aim of optimizing the seedlings production conditions. A randomized complete blocks of six types of substrate containing black soil, charcoal and sawdust, was set up. Seedlings of three weeks old were transplanted in the alveolate plates with various substrates during the education phase until the age of plantation. 30 g of a mineral fertilizer NPK (20-20-20) diluted in 10 l of water was brought daily to the seedlings. The results showed a substrate effect on the biomass and the plants growth. Seeedlings which growed on the substrate 6 (75% black soil + 25% charcoal) and 4 (50% black soil + 50% charcoal) present the best growth performances. The Acetylene Reduction Assay (ARA) realized was significantly influenced by the types of substrate. Mineral fertilizer brought does not generate the abortion of the nodules. The substrate 5 (black soil 50%, charcoal 25% and sawdust 25%) offered the optimum conditions of nodules development.Keywords: Substrate, Acacia mangium, biomass, ARA.

L’aulacodiculture est une option privilégiée à la fourniture de protéines animales. Cette étude a été menée dans le but de déterminer l’effet d’un aliment granulé sur les caractéristiques organoleptiques et biochimiques de leur viande. Ainsi, un lot d’aulacodes a été nourri au granulé tandis que l’autre nourri au fourrage avec complément alimentaire (aliment classique). Après un abattage normal, les membres antérieurs et postérieurs des animaux ont été prélevés. La viande des membres postérieurs a été retenue pour l’analyse organoleptique (couleur, texture, jutosité, flaveur, tendreté) par 12 panelistes en trois répétitions. La viande des membres antérieurs a servi à la détermination de la matière sèche, des protéines brutes, de la matière grasse et des cendres brutes. Ces travaux montrent que la viande d’aulacode est juteuse, tendre avec une texture grossière et une flaveur prononcée quel que soit le type d’aliment. Le profil sensoriel montre une différence tant au niveau de la couleur qu’au niveau de la jutosité et de la texture. Quant aux paramètres biochimiques, aucune différence significative n’a été observée (p ≥ 0,05). Il convient de retenir que la viande d’aulacodes nourris au granulé a été plus appréciée tant pour la couleur, la texture, la jutosité que pour la flaveur. Mots clés : Aulacodes, viandes, granulé, fourrage, Côte d’Ivoire.

English Title: Some organoleptic characteristics and nutritional values and nutritionals values of meat of Thryonomys swinderianus, (Temminck, 1827) raised in captivity and fed with two types of foodGrasscutter farming seems to be a preferred option for the supply of proteins formerly derived from hunting. This study aimed at determining the effect of a granulated food on the organoleptic and biochemical qualities of grasscutter meat. Thus, three grasscutters were randomly selected from a batch of animals fed with a granulated food and the other three from the batch fed with the conventional food. After normal slaughter, the fore and hind limbs were removed. The meat of the posterior limbs was selected for organoleptic analysis by a panel of 12 consumers in three repetitions. The meat from upper limbs was used to evaluate the biochemical parameters such as dry matter, crude protein, fat and raw ash. Results showed that the meat of the grasscutter was juicy, tender with a coarse texture and a pronounced flavor whatever the type of food. The sensory profile showed a significant difference in color, juiciness, and texture of meat. With respect to biochemical parameters, no significant difference was observed (p ≥ 0.05). The type of food had no effect on biochemical parameters of grasscutter meat. However, the organoleptic parameters influenced significantly the level of appreciation of grasscutter meat.

DigiExplanation driven assignments for personalising learning in construction education
Authors: Kamardeen Imriyas , Samaratunga Marini 
Published: September 2020

Personalising learning is critical for universities to achieving excellence in education. It entails maintaining an education system that is responsive to the learning needs, aptitudes and interests of individual students. Rather than imposing a ‘one-size fits all’ model, personalising learning is anticipated to ensure that every learner achieves his/her highest potential. Pedagogical literature suggests that learning-oriented assessments that are engaging, authentic and relevant are an effective mode for personalisation. DigiExplanations is a novel approach that requires students to create short digital media to communicate their ideas to ordinary audiences. It offers an opportunity for research-based authentic learning by harnessing digital media that exist outside of their institution and their digital competencies to create personally relevant and interesting resources. The aim of the research was to investigate the effectiveness of digiExplanations driven assessments for improving personalised learning in construction education. A case study strategy was adopted in the research. A first-year subject from the construction management degree was chosen as the case, which had a class of 159 students. A new assignment scheme was introduced for which students were required to develop digiExplanations in groups of five. The assessment criteria comprised: rationale for the study; depth and breadth of the discussions for the topic; appropriateness of media used in the discussions; creativity in the use of media (storyboarding); design of digiExplanation; quality of conclusion; and proper acknowledgement of materials used. After the submission deadline, an online survey was conducted with the students to assess how the new assessment approach facilitated personalised learning. Several findings emerged from the study. The digiExplanations based assignment provided similar learning experiences for students with different characteristics concerning their first language, domestic/international student status, work situation and digital competencies. Moreover, the study found that some considerations are more significant than others in designing assessments that can drive personalised learning, which are: personally relevant/interesting, engagement, harnessing internet resources and progressive feedback. The survey findings further suggest that while the new pedagogical approach achieved its intended aim, few students perceived it a cumbersome method as it required more efforts than traditional assignments.
DSCOVR/EPIC-derived global hourly and daily downward shortwave and photosynthetically active radiation data at 0.1° × 0.1° resolution

Published: September 2020

Abstract. Downward shortwave radiation (SW) and photosynthetically
active radiation (PAR) play crucial roles in Earth system dynamics.
Spaceborne remote sensing techniques provide a unique means for mapping
accurate spatiotemporally continuous SW–PAR, globally. However, any
individual polar-orbiting or geostationary satellite cannot satisfy the
desired high temporal resolution (sub-daily) and global coverage
simultaneously, while integrating and fusing multisource data from
complementary satellites/sensors is challenging because of co-registration,
intercalibration, near real-time data delivery and the effects of
discrepancies in orbital geometry. The Earth Polychromatic Imaging Camera
(EPIC) on board the Deep Space Climate Observatory (DSCOVR), launched in
February 2015, offers an unprecedented possibility to bridge the gap between
high temporal resolution and global coverage and characterize the diurnal
cycles of SW–PAR globally. In this study, we adopted a suite of
well-validated data-driven machine-learning models to generate the first
global land products of SW–PAR, from June 2015 to June 2019, based on
DSCOVR/EPIC data. The derived products have high temporal resolution
(hourly) and medium spatial resolution (0.1∘×0.1∘), and they include estimates of the direct and diffuse components
of SW–PAR. We used independently widely distributed ground station data from
the Baseline Surface Radiation Network (BSRN), the Surface Radiation Budget
Network (SURFRAD), NOAA's Global Monitoring Division and the U.S. Department
of Energy's Atmospheric System Research (ASR) program to evaluate the
performance of our products, and we further analyzed and compared the
spatiotemporal characteristics of the derived products with the
benchmarking Clouds and the Earth's Radiant Energy System Synoptic (CERES)
data. We found both the hourly and daily products to be consistent with
ground-based observations (e.g., hourly and daily total SWs have low biases
of −3.96 and −0.71 W m−2 and root-mean-square errors (RMSEs) of 103.50
and 35.40 W m−2, respectively). The developed products capture the
complex spatiotemporal patterns well and accurately track substantial
diurnal, monthly, and seasonal variations in SW–PAR when compared to CERES
data. They provide a reliable and valuable alternative for solar
photovoltaic applications worldwide and can be used to improve our
understanding of the diurnal and seasonal variabilities of the terrestrial
water, carbon and energy fluxes at various spatial scales. The products are

Authors: Núñez Rodr´´íguez José 
Published: September 2020

Introducción: La gamificación como estrategia de aprendizaje en contextos educativos, consiste en aprovechar los elementos propios de los juegos para lograr un aprendizaje significativo. Métodos: Se presentó una estrategia didáctica para la identificación taxonómica de dípteros de importancia forense dirigida a estudiantes de bachillerato y egresados, a través del uso de la plataforma Edmodo por medio de las actividades: sopa de letras, pareamiento para el aprendizaje del vocabulario y características morfológicas de dípteros, por lo tanto, para valorar el desempeño se crearon insignias clasificándose en tres niveles principiante, intermedio o experto. Por otro lado, se realizó una actividad práctica presencial para la colecta e identificación de los dípteros presentes en vísceras de res, culminando con la aplicación de un cuestionario a los 27 participantes. Resultados: El 74.1% de los estudiantes fueron clasificados como expertos al cumplir con todas las actividades propuestas en la plataforma, mientras que el 91.9% de los estudiantes acertó con la identificación taxonómica de los dípteros adultos e inmaduros asignados durante la actividad práctica, esta sirvió para consolidar el aprendizaje adquirido durante la gamificación. Conclusión: Esta estrategia influyó positivamente sobre el aprendizaje memorístico de las características morfológicas de los dípteros de importancia forense, sin embargo, se requiere mayor tiempo de actividades prácticas para el aprendizaje de la clasificación de insectos, debido a la diversidad de especies presentes en un cuerpo humano sin vida.
Effect of shooting experience on executive function: differences between experts and novices
Authors: Shao Mingming , Lai Yinghui , Gong AnMin , Yang Yuan , Chen Tingting , Jiang Changhao 
Published: September 2020

Background
Executive function (EF) plays an important role in controlling human actions. Shooting is a closed motor skill, characterized by high anti-interference ability and high mental intensity. However, the beneficial effects of closed exercises such as shooting on EF remain unclear.

Methods
We utilized an expert-novice paradigm and the Flanker task to examine the EF of shooting athletes. Participants were assigned into the novice group, expert group, or control group, based on the level of training and competition experience. Reaction time (RT) and accuracy of performance across the three groups were compared.

Results
For the simple task, the control group showed a longer RT than the novice group, for all three inter-stimulus interval (ISI) conditions. Significant differences between the control and the expert groups were observed only at 300-ms and 400-ms ISIs. For the complex task, the control group exhibited a higher RT than the novice and expert groups at the 300- and 400-ms ISIs.

Conclusions
The self-control during performing closed motor skills in the environment determines that shooters have proficient anti-interference ability. This ability is uncorrelated with task type, but most likely is affected by reserved task response time.
Proanthocyanidins reduce cellular function in the most globally diagnosed cancers in vitro
Authors: Albogami Sarah 
Published: September 2020

Background
Growing evidence indicates that proanthocyanidins (PACs) may be effective in treating and preventing various cancers. The fundamental mechanism of PACs inhibiting the proliferation at cellular and molecular levels in most of the cancer types remains unclear.

Objective
The anticancer efficacy of PACs was investigated in vitro using three human cancer cell lines: human colorectal adenocarcinoma (HT-29), human breast carcinoma (MCF-7), and human prostatic adenocarcinoma (PC-3).

Methods
Cytotoxicity was evaluated by MTT assay, while cell proliferation was measured by trypan blue exclusion method. Cell migration was measured by wound healing assay, and DAPI staining was used to evaluate apoptotic nucleus morphology. RT-PCR was used to analyze the expression of Bax and Bcl-2, and caspase enzyme activity assay was measured by caspase colorimetric assay.

Results
PACs could inhibit both cellular viability and proliferation in a concentration- and time-dependent fashion in all investigated cells. Further, all tested cells showed similarly decreased migration after 24- and 48-h PAC treatment. We observed increased apoptotic nucleus morphology in treated cells (p ≤ 0.01). BAX expression significantly increased in HT-29 (p < 0.01), PC-3(p < 0.01), and MCF-7 (p < 0.05) cells, while BCL-2 expression significantly declined (p < 0.05). Caspase activities were significantly increased in all tested cancer cell lines after 24-h PAC treatment.

Conclusion
PACs may have potential therapeutic properties against colorectal, breast, and prostate cancer.
Carbon emission and water use efficiency response to tillage methods and planting patterns of winter wheat in the North China Plain
Authors: Ma Yuzhao , Li Quanqi 
Published: September 2020

Background
Implementing sustainable farming practices for winter wheat (Triticum aestivum L.) in the North China Plain may be a way to reduce carbon emissions. No tillage generally results in less net CO2 loss from farmland, but no tillage also reduces the grain yield and water use efficiency (WUE) of winter wheat. Wide-precision planting of winter wheat may enhance the grain yield and WUE; however, it is not known precisely how tillage and planting patterns affect CO2 exchange, grain yield and WUE.

Methods
In this study, two tillage methods (conventional tillage, T and no tillage, NT) and two planting patterns (conventional planting, C and wide-precision planting, W) were used in two consecutive winter wheat growing seasons.

Results
Compared with the T treatments, the NT treatments had significantly lower cumulative net CO2 emissions in 2015–2016 and 2016–2017 (30.8 and 21.3%, respectively), and had lower grain yields (9.0 and 9.4%, respectively) and WUE (6.0 and 7.2%, respectively). The W treatments had a compensating effect on grain yield failure and reduced cumulative net CO2 emissions more than C treatments, thereby increasing WUE, reducing carbon emissions per unit water consumption, and increasing the yield carbon utilization efficiency (YCUE). The lowest cumulative CO2 emissions and highest YCUE were observed for NT with W treatment. Results from this analogous tillage experiment indicated that NT and W farming practices provide an option for reducing carbon emissions and enhancing WUE and YCUE for sustainable winter wheat development.

Introduction: The importance of contraception amongst adolescents cannot be over-emphasized especially as it concerns reproductive health. Globally, these group of persons are vulnerable and engage in high risk sexual behaviour with little or no access to contraception particularly in the developing countries of the world.
Aim: To determine the access to contraception amongst female adolescents in Rivers State.
Methods: It was a cross sectional study of female adolescents attending holiday camp in Port Harcourt, Rivers State. Questionnaires were distributed and information coded and analysed using SPSS version 22.
Results: One hundred questionnaires were distributed and 89 retrieved. The mean age was 16 ± 2 years. Fifty seven (64.0%) were in secondary school while 32(36.0%) of the adolescents were undergraduates. Twelve (13.5%) were sexually active compared to 69 (77.5%) who were not sexually active, 8 (9%) were non respondents to this question. One (1.1%) of the adolescents had access to contraception while 85 (95.5%) had no access to contraception, 3 (3.3%) did not give any response as regards to access to contraception or not. The media was the most common means of information 25 (28%) on contraception.
Conclusion: The study revealed that access to contraception amongst female adolescents in Port Harcourt was poor. Enlightenment programme is highly recommended to prevent unwanted pregnancies, sexually transmitted infections and other adverse effects on reproductive health.
