Abstract:
This study investigated the effect of practical drawing as difficult concept on students’ academic performance drawing as difficult concept on students’ academic performance in Biology in Calabar Education zone, Cross River State, Nigeria. Quasi experimental design of pretest, post test, control group non randomize equivalent groups was adopted for the study. Two null hypotheses were formulated and tested t 0.05 level of significance. Simple random sampling was used to select four public secondary schools from the research area and Biology respondents that were used. Intact class was used. The instrument use for data collection was Biology Achievement test (BAT) in form of thirty (30) multiple choice questions Data collected were analyzed using mean, standard deviation and analysis of covariance (ANCOVA). The findings revealed that there is a significant effect of practical drawing on students academic performance. Gender was not a significant factor in the students’ achievement. It was recommended among others that; Biology teachers should be encouraged through workshops seminar, retraining programmes on practical drawing pedagogical content mastery and presentation to promote students’ academic performance in Biology.

Abstract:
Les pesticides botaniques utilisés dans le contrôle des insectes ravageurs des cultures constituent de nos jours, une alternative aux pesticides de synthèse. Cette étude vise à évaluer l’efficacité du Top bio et de l’huile de Thevetia dans la lutte contre les ravageurs carpophages du cotonnier. Le dispositif expérimental est constitué des Blocs de Fisher avec 6 objets et 4 répétitions. Les objets comparés sont ‘’Non Traité’’, l’agri-bio-pesticide dosé à 1 l/ha, deux doses de Top bio (2 l/ha et 3 l/ha) et deux doses (1% et 2%) de l’huile de Thevetia. Les modèles linéaires généralisés ou non, à effets mixtes ou fixes ont été utilisés pour déterminer l’influence des objets sur les chenilles carpophages et leurs dégâts à Gobé. Le nombre de chenilles de Helicoverpa armigera a varié de 0,15 (top bio 3 l/ha et huile de Thevetia 2%) à 1,5 (Non traité) en 2015. Le nombre de chenilles de Earias biplaga a oscillé entre 2,81 (huile de Thevetia 2%) et 5,84 (Non traité) en 2016. Le nombre de chenilles de Pectinophora gossypiella a varié de 0,75 (agri-bio-pesticide) à 3,45 (Non traité) en 2015. Le nombre de chenilles de Thaumatotibia leucotreta a oscillé entre 2,28 (Top bio 2 l/ha) et 8,00 (Non traité) en 2016. Le pourcentage de capsules vertes saines a varié de 14,25±2,8% (Non traité) à 26,25±2,8% (huile de Thevetia). Le pourcentage de capsules mûres chenillées a varié de 39,85±8,90% (Top bio 2 l/ha) à 64,96±4,90% (Non traité). Les biopesticides comparés ont été efficaces sur H. armigera, E. biplaga, P. gossypiella à leur faible dose. Mais la dose de 1% de l’huile de Thevetia a été inefficace sur T. leucotreta qui a été contrôlé par la dose de 2%. Ces biopesticides se positionnent comme une alternative dans la lutte contre les chenilles carpophages en culture cotonnière biologique.

Abstract:
Context and Objective: A plantation control trial was carried out against the vector of foliar desiccation, Helopeltis sp in Côte d’Ivoire.
Material and Methods: A survey in cashew orchard was carried out in Béré, Poro, Hambol and Marahoué Regions. Buds showing attacks of Helopeltis sp were collected to isolate fungus. A biological control test was carried out in situ on Helopeltis sp in Dikodougou, Napié and Tortiya. The test used an essential oil, 30 mg/l Ocimum gratissimum, the synthetic pesticides based on 100 g/l Chlorantraniliprole + 200 g/l Thiamethoxam and 200 g/l Cypermethrin + 200 g/l Acetamiprid.
Results: All the dried cashew leaf buds procured fungal isolates of Lasiodiplodia theobromae. Chlorantraniliprole+Thiamethoxam and Ocimum gratissimum showed the best efficacy against Helopeltis sp at 300 ml/ha. Damage of the pest was reduced more than 10% for the Ocimum gratissimum compared to the untreated control. The economic gain generated by the biopesticide was more than 5000 F CFA.ha-1 compared to the untreated control.
Conclusion: These results suggest the adoption of the biopesicide Ocimum gratissimum and Chlorantraniliprole+Thiamethoxam at a dose of 300 ml/ha in the protection of cashew trees against the mosquito, Helopeltis sp, vector of cashew foliar desiccation due to Lasiodiplodia theobromae.
Keywords: Cashew, Helopeltis sp, Lasiodiplodia theobromae, biopesticide, Cote d’Ivoire.


Stratégies pour Atténuer la Pandémie du Covid-19 : Quelles Approches pour Quels Impacts

Mohammed Boukhir
Abstract:
Etant donné qu’il n’existe pas de vaccin contre le coronavirus, les autorités de pays touchés par ce virus ont adopté des mesures qu’ils estiment nécessaires pour freiner la propagation de la pandémie. Certains pays ont choisi la stratégie de suppression, alors que d’autres ont préféré la stratégie d’atténuation. Ainsi, les pays qui ont choisi la stratégie de suppression, ont obtenu de meilleurs résultats et un taux de mortalité très faible. En revanche, ceux qui ont préféré la stratégie d’atténuation, ont connu un nombre de morts relativement important. Cependant, les mesures prise par les décideurs politiques ont un impact plus ou moins limité. Donc, pour arriver à un optimal de ces mesures établies contre la pandémie, il faudra une certaine complémentarité des différentes interventions. Donc, plus on a des mesures synchronisées, plus leur impact sera positivement optimal sur l’évolution de l’épidémie. Néanmoins, l’optimisation de l’efficacité de telles mesures peut être influencée par d’autres facteurs comme la qualité du système sanitaire, le type de traitement choisi par les médecins, ou encore des comorbidités préexistantes dans chacun des pays concernés par l’épidémie. Enfin, certains facteurs peuvent influencer l’évolution de l’épidémie comme la densité de la population, la moyenne d’âge de la population, et l’état de santé de la population le facteur de la pollution de l'air.

COVID-19 transmission: can blood-feeding arthropods contribute in spreading the disease to humans?

Nighat Perveen, Sabir Bin Muzaffar and Mohammad Ali Al-Deeb
Abstract:
Until now, there are no reports of COVID-19 transmission by blood-feeding arthropods. It is known that mosquitos can transmit several viral diseases such as Zika and West Nile virus. But it is also known that some viruses are not transmitted by mosquitos such as HIV (human immunodeficiency virus). Currently, scientists believe that the COVID-19 disease started in wild animals and then it infected humans after interacting with them possibly in animal markets. In this short communication, we discuss the role of some blood-feeding arthropods in disease transmission and if they may contribute to the transmission of COVID-19. It is important to examine such a scenario, although it remains hypothetical thus far.
Keywords: Coronavirus transmission, COVID-19, SARS-CoV-2, tick vector, vector reservoir, vector-to-human transmission.


Theoretical Half-life Time and Alpha Energies of the Elements: Part-7; Z=100–107 (Fm–Bh)—Island of Stability

Bahjat R. J. Muhyedeen
Abstract:
This paper is the seventh part of a series of eleven of QAM-UQAM-NMT-2017-Ver-3 & 4. It is based on the novel mass quantization and the variable neutron mass concepts of my new nuclear theory, the Nuclear Magneton Theory of Mass Quantization, NMT. Three methods for prediction of the α-decay half-life formulae, the Viola-Seaborg, the Royer GLDM, and the Sobiczewski-Parkhomenko, are applied to evaluate the half-life of the atomic masses theoretically calculated. NMT found out 115 isotopes that have long T1/2 and 20 isotopes exceed 1010 year. NMT considered them as part of the Island of stability. In the previous article, the new quantized atomic masses, and their α-energies of the 800 nuclides belonging to Z=100–107 (Fm–Bh) have been explained in detail.
Keywords: Half-life, alpha decay atomic masses, new isotopes, superheavy nuclei.


The Teleological Difference between Men and Women; a Cultural Conception or a Biological Distinction? - An Analysis of the Jurisprudence of Gender Equality, with a Focus on the Shortcomings of the Sameness-Difference Debate

Keshya Melana Amarasinghe
Abstract:
This paper demonstrates how both sides of the sameness-difference debate are individually inadequate in dealing with the natural and cultural differences that stymie gender equality, and also how the approach as a whole fail, due to its subconscious acceptance of a male-dominated society. In doing so, it is evident that the differences that the said society attributes to be present between women and men are fundamentally cultural decisions; the few natural ones twisted to fit our phallocentric society’s hierarchy. Finally, this paper evaluates proposed alternatives to this ‘difference doctrine’ and the practical solutions they offer for gender inequality.
Keywords: Gender equality, sameness-difference debate, sex equality.
