The Impact of Project-Based Learning on Students’ Cultural Awareness
Authors: AKHARRAZ Mohamed 
Published: June 2021

While only a few studies have been conducted to explore the effectiveness of project-based learning (PjBL) in culture teaching/learning in second and foreign language education, no study known to the investigator has empirically measured the effect of PjBL together with the cultural framework of the 3Ps (products, practices, and perspectives) in the teaching of culture in an EFL context. This study aimed to measure the effect of PjBL on students’ awareness of the English cultures. Two intact groups at a Moroccan public school were randomly assigned to control and treatment groups. A cultural awareness test was utilized to measure students’ cultural awareness levels before and after a 24-week treatment. The independent sample t-tests indicated that the PjBL group substantially outperformed the control group in cultural awareness. While the study concluded that PjBL is a useful tool for incorporating cultures in the EFL classes, its proper implementation entails a redistribution of power in the language classroom and a radical change in the culture of assessment.

This study aims to determine the effect of modification of the Honda Tiger 2000 on exhaust emissions of CO and HC. The method used is to modify the carburettor venturi piston and replace the rocker arm with a roller rocker arm. The exhaust emission test used a gas analyzer type SUKYOUNG SY-GA 401. The object of the study was a Honda Tiger 2000 motorcycle. The results showed that modification of the Honda Tiger 2000 motorcycle at idle, 1000 rpm, 1500 rpm, and 2000 rpm increased CO emissions but reduced HC emissions. Based on comparing the motorcycle emission threshold values for manufacture ≤ 2010, namely CO emissions exceeding 5.5% and HC emissions less than 2400 ppm. Pertamax Turbo fuel consumption is more efficient than Pertalite with a distance ratio of 45 km requiring 1L Pertamax Turbo and 1.4L Petalite.

Published: June 2021

Resumen

Introducción y objetivos. La malabsorción e intolerancia a los hidratos de carbono producen síntomas inespecíficos, siendo el test de hidrógeno espirado (THE) el método diagnóstico de elección. El objetivo del estudio fue conocer las características clínicas y epidemiológicas de esta patología.

Material y métodos. Estudio observacional, descriptivo y retrospectivo de pacientes que se realizaron el THE en el Hospital de Jerez de la Frontera entre julio de 2017 y diciembre de 2018.

Resultados. Se incluyeron 353 pacientes, sin hallarse asociaciones significativas entre edad, sexo e IMC con la presencia de malabsorción o intolerancia. La malabsorción más frecuente fue de lactosa (30,2%), así como los grados leves (I). Fue estadísticamente significativa la asociación entre malabsorción de fructosa y sorbitol. Con respecto a las intolerancias, también fue la más frecuente a la lactosa (17,8 % de los pacientes), siendo estadísticamente significativas las asociaciones entre intolerancia a lactosa y fructosa; e intolerancia a fructosa y sorbitol. Los síntomas digestivos más frecuentes por los que se indicó el THE fueron la diarrea (42,9%), el dolor abdominal (29,1%) y la distensión abdominal (20,3%), sin existir asociación significativa de que alguno fuera un síntoma predictor de un THE positivo.

Conclusiones. La malabsorción y la intolerancia a lactosa, fructosa y sorbitol son frecuentes en nuestro medio siendo causantes de síntomas digestivos que con frecuencia son motivos de consulta. Disponemos de un método sencillo de diagnóstico, pero no de síntomas predictivos que sean determinantes de esta patología.
Syntax, morphosyntax, and serial recall: How language supports short-term memory
Authors: Schweppe Judith , Schütte Friederike , Machleb Franziska , Hellfritsch Marie 
Published: June 2021

AbstractIn the classic view of verbal short-term memory, immediate recall is achieved by maintaining phonological representations, while the influence of other linguistic information is negligible. According to language-based accounts, short-term retention of verbal material is inherently bound to language production and comprehension, thus also influenced by semantic or syntactic factors. In line with this, serial recall is better when lists are presented in a canonical word order for English rather than in a noncanonical order (e.g., when adjectives precede nouns rather than vice versa; Perham et al., 2009, Quarterly Journal of Experimental Psychology, 62[7], 1285–1293). However, in many languages, grammaticality is not exclusively determined by word order. In German, an adjective–noun sequence is grammatical only if the adjective is inflected in congruence with the noun’s person, number, and grammatical gender. Therefore, we investigated whether similar effects of syntactic word order occur in German. In two modified replications of Perham et al.’s study, we presented lists of three pairs of adjectives and nouns, presented in adjective–noun or in noun–adjective order. In addition, we manipulated morphosyntactic congruence between nouns and adjectives within pairs (Exp. 1: congruently inflected vs. uninflected adjectives; Exp. 2: congruently inflected vs. incongruently inflected adjectives). Both experiments show an interaction: Word order affected recall performance only when adjectives were inflected in congruence with the corresponding noun. These findings are in line with language-based models and indicate that, in a language that determines grammaticality in an interplay of syntactic and morphosyntactic factors, word order alone is not sufficient to improve verbal short-term memory.

Acetylene derivatives of 1,2,4-oxadiazoles, 5-(2-arylethynyl)-3-aryl-1,2,4-oxadiazoles, have been obtained, for the first time, from 5-(2-arylethenyl)-3-aryl-1,2,4-oxadiazoles by their bromination at the carbon-carbon double bond followed by di-dehydrobromination with NaNH2 in liquid NH3. Reaction of the acetylene 1,2,4-oxadiazoles with arenes in neat triflic acid TfOH (CF3SO3H) at room temperature for 1 h result in the formation of E-/Z-5-(2,2-diarylethenyl)-3-aryl-1,2,4-oxadiazoles as products of regioselective hydroarylation of the acetylene bond. Addition of TfOH to acetylene bond of these oxadiazoles gives rise quantitatively to E-/Z-vinyl triflates. Reaction cationic intermediates have been studied by DFT calculations. The reaction mechanisms have been discussed.

Published: June 2021

Objective: Breastfeeding is a cost-effective and evidence-based public health intervention for the control of childhood malnutrition and its consequences. Partners’ support and attitude towards breastfeeding is an important determinant of breastfeeding initiation, continuity, and outcome. This study assessed the perception of breastfeeding and its support among male students in Sagamu, Nigeria.
Method: A cross-sectional study was carried out among 300 male undergraduate students in Sagamu, selected via systematic sampling. Data were collected with the aid of a structured, self-administered questionnaire and analyzed using SPSS 21.0, with results presented as frequencies and proportions.
Result: The mean age of respondents was 20±3.5 years. All respondents felt it was important for women to breastfeed their infants; 42% of respondents felt breastfeeding interfered with work; 20% felt women should be entitled to paid maternity leave; 85% will support efforts to promote breastfeeding in public; 95% will encourage their partners to breastfeed while working outside the home; 92% will assist their breastfeeding partners with household chores.
Conclusion: Respondents had a good perception of breastfeeding and were willing to support its practice at home, work, and in the community. Adequate engagement of men in nutrition education activities will be most effective in promoting and protecting breastfeeding.
Impact of Economic and Noneconomic Factors on Inflow of Remittances into Bangladesh
Authors: Rahman Md. Hasanur , Habib Ahsan 
Published: June 2021

Purpose: Remittance plays an important role in the economy of Bangladesh. It also contributes to the change in the social structure and standard of living. The purpose of the study is to identify the economic and non-economic determinants of the remittance inflow into Bangladesh.
Methodology: The study considered two types of variables as the determinants of the remittance inflow: economic and non-economic. Economic determinants of remittances inflows included exchange rate, education, economic growth rate, and market interest rate. The non-economic determinants covered control of corruption, government effectiveness, and political stability. Monthly data were used for the case of economic determinants from 2014 to 2020 and annual data were used in the case of non-economic determinants from 1996 to 2018. The marginal effect of each variable has been analyzed by using the Robust Least Squares (RLS) method.
Results: The estimated results of this study state that, economic determinants like capital formation and education factors have a positive and significant impact on remittances inflows in both static and dynamic cases. However, the exchange rate does not create a positive impact due to volatility. The RLS estimation shows the control of corruption has a positive impact on remittances inflows whereas government effectiveness and political stability hurt remittances inflows in Bangladesh.
Implications: The current study identified the significant determinates of remittances inflows in Bangladesh. The findings have implications for policy formulation as regard remittances and non-resident Bangladeshis.
Self-consistent 3D Supernova Models From −7 Minutes to +7 s: A 1-bethe Explosion of a ∼19 M
⊙ Progenitor
Authors: Bollig Robert , Yadav Naveen , Kresse Daniel , Janka Hans-Thomas , Müller Bernhard , Heger Alexander 
Published: June 2021

Abstract
To date, modern three-dimensional (3D) supernova (SN) simulations have not demonstrated that explosion energies of 1051 erg (=1 bethe=1 B) or more are possible for neutrino-driven SNe of non/slow-rotating M < 20 M
⊙ progenitors. We present the first such model, considering a nonrotating, solar-metallicity 18.88 M
⊙ progenitor, whose final 7 minutes of convective oxygen-shell burning were simulated in 3D and showed a violent oxygen–neon shell merger prior to collapse. A large set of 3D SN models was computed with the Prometheus-Vertex code, whose improved convergence of the two-moment equations with Boltzmann closure allows now to fully exploit the implicit neutrino-transport treatment. Nuclear burning is treated with a 23-species network. We vary the angular grid resolution and consider different nuclear equations of state and muon formation in the proto-neutron star (PNS), which requires six-species transport with coupling of all neutrino flavors across all energy–momentum groups. Elaborate neutrino transport was applied until ∼2 s after bounce. In one case, the simulation was continued to >7 s with an approximate treatment of neutrino effects that allows for seamless continuation without transients. A spherically symmetric neutrino-driven wind does not develop. Instead, accretion downflows to the PNS and outflows of neutrino-heated matter establish a monotonic rise of the explosion energy until ∼7 s post-bounce, when the outgoing shock reaches ∼50,000 km and enters the He layer. The converged value of the explosion energy at infinity (with overburden subtracted) is ∼1 B and the ejected 56Ni mass ≲0.087 M
⊙, both within a few 10% of the SN 1987A values. The final NS mass and kick are ∼1.65 M
⊙ and >450 km s−1, respectively.

Abstract
A full understanding of high-mass star formation requires the study of one of the most elusive components of the energy balance in the interstellar medium: magnetic fields. We report Atacama Large Millimeter/submillimeter Array (ALMA) 1.2 mm, high-resolution (700 au) dust polarization and molecular line observations of the rotating hot molecular core embedded in the high-mass star-forming region IRAS 18089−1732. The dust continuum emission and magnetic field morphology present spiral-like features resembling a whirlpool. The velocity field traced by the H13CO+ (J = 3−2) transition line reveals a complex structure with spiral filaments that are likely infalling and rotating, dragging the field with them. We have modeled the magnetic field and find that the best model corresponds to a weakly magnetized core with a mass-to-magnetic-flux ratio (λ) of 8.38. The modeled magnetic field is dominated by a poloidal component, but with an important contribution from the toroidal component that has a magnitude of 30% of the poloidal component. Using the Davis–Chandrasekhar–Fermi method, we estimate a magnetic field strength of 3.5 mG. At the spatial scales accessible to ALMA, an analysis of the energy balance of the system indicates that gravity overwhelms turbulence, rotation, and the magnetic field. We show that high-mass star formation can occur in weakly magnetized environments, with gravity taking the dominant role.

BACKGROUND: Population aging is considered to be a global phenomenon today. Age-associated immune system dysfunction or “immunosenescence” is indicated by increased susceptibility to infections and chronic diseases, such as hypertension, diabetes mellitus, autoimmune diseases, heart disease, and atherosclerosis. One of the immunosenescence markers is a significant drop in CD28 and reduced proinflammatory cytokine interleukin-2 (IL-2). The mango mistletoes are deemed to have a better affinity for docking the CD28 and IL-2R receptors of α and β subunits than other plants.

AIM: This study aims to determine the effect of ethanol extract of mango mistletoes on IL-2 levels, the percentage of CD4+CD28+, and the percentage of CD8+CD28+ in aged female mice.

METHODS: The leaves of mango mistletoes were extracted using 96% ethanol solvent, and the extract was administered to aged female mice (18–20 months) orally with different doses for each group, namely 150, 300, and 600 mg/kg. Mango mistletoe leaves extract was administered once a day for 14 days. Then, the IL-2 levels of the mice were checked from their heart blood samples using Enzyme-Linked Immunosorbent Assay, while the percentages of CD4+CD28+ and CD8+CD28+ were examined from the spleen samples using flow cytometry.

RESULTS: The ethanol extract of mango mistletoe leaves was able to increase the percentage of CD4+CD28+ significantly (p < 0.05) at doses of 300 and 600 mg/kg and increase the percentage of CD8+CD28+ significantly (p < 0.05) at a dose of 600 mg/kgBW, while other various doses had a strong enough correlation (r = 0.48) to increase IL-2 levels.

CONCLUSION: The ethanol extract of mango mistletoe leaves has the good potential to inhibit the aging process in the immune system, as characterized by an increase in IL-2 levels and the percentage of CD4+CD28+ and CD8+CD28+.

L’urgence que représente la compréhension de la pandémie de Covid-19 a entraîné des différences considérables entre les procédures de collecte des données des pays concernés, qui s’efforcent tous de produire des informations en temps réel mais qui restent des statistiques de mortalité imparfaites. Pour remédier à ce problème, l’analyse porte sur les décomptes de décès par Covid-19 provenant de la base de données « La démographie des décès par Covid-19 » ( https://dc-covid.site.ined.fr/fr/ ) ainsi que leurs limites. Cet article souligne des aspects importants touchant aux données qui limitent la possibilité de mener des comparaisons internationales. Pour pallier ces difficultés, les sources sont classées en fonction du caractère exhaustif de leurs données, puis les décomptes de décès sont analysés et comparés pour 16 pays. Bien comprendre les caractéristiques de la collecte des données est fondamental pour le traitement des statistiques imparfaites.

Published: June 2021

La presente investigación ahonda en el tratamiento integral de fuentes geohistóricas textuales, impulsando los procedimientos que en la actualidad abogan por la recuperación, análisis y apertura del conocimiento científico de forma abierta y extensiva a la sociedad. Entre mediados del siglo XVIII y mediados del XX se elaboran en España más de cuatrocientas obras médicas (geografías o topografías médicas), al socaire de la generalización de las teorías higienistas en el urbanismo y la sociedad en su conjunto. Estas ediciones, bien estudiadas y conocidas, constituyen unas colecciones de información y documentación enormemente valiosa para el conocimiento de los espacios, urbanos y rurales, de la época.
Así, la información contenida en la Geografía médica de Degaña, de 1913, se utilizará como base para el análisis de la información que, a escala geográfica, aporta esta tipología documental, estableciendo una metodología para la extracción de información geográfica contenida en los documentos de principios del siglo XX. Este proyecto busca optimizar el uso de fuentes secundarias de conocimiento sobre el territorio, teniendo en cuenta la variedad y cantidad de información que se puede extraer de ellos. Con el uso de fuentes secundarias de información, se abren nuevas oportunidades y estrategias para abordar problemas territoriales desde los amplios campos de la geografía histórica, la humana y la geografía regional.
